We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare preoperative and postoperative visual acuity (VA) and intraocular pressure (TOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean logMAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively ( P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.

Abstract Purpose: To evaluate the anatomical effects of implantable phakic contact lens (IPCL) (Care Group, India) on anterior segment and its visual outcomes .Patients and methods: In a prospective interventional case series study, 60 highly myopic eyes of 32 patients were subjected to IPCL implantation in the Ophthalmology Department of Minia University Hospital, Egypt from January 2019 to June 2021. All patients had complete ophthalmic examination and were followed up for 1 year. Pentacam was used for preoperative and postoperative estimation of anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV) and IPCL vault in the 1st, 3rd, and 12th months. Assessment of corneal endothelium was done using specular microscope preoperatively and after 12 months. Preoperative and postoperative refraction and visual acuity were measured. Results: There was a statistically significant decrease in ACD, ACA, and ACV. There was no significant difference between preoperative and postoperative mean intraocular pressure (IOP) by the 12th month (P=0.163). The mean preoperative endothelial cell count (ECD) was significantly reduced from 2929.3±248 cells/mm2 to 2737.9±303 cells/mm2 at the 12th month (P<0.001). with a statistically highly significant improvement of mean Log Mar uncorrected visual acuity (UCVA) from 1.48±0.19 preoperatively to 0.46±0.11 by the end of follow up (P<0.001) with insignificant difference between preoperative best corrected visual acuity (BCVA) and postoperative UCVA (P=0.209). In the 12th month, the mean vault was 240±540 μm. No sight threatening complications occurred.Conclusion: Although IPCL induced anatomical changes, it was safe and effective for correction of high myopia.

Objective: To evaluate the visual outcomes and intraocular pressure changes after Visian Implantable Collamer Lens (ICL) implantation V4b and V4c (with centraflow technology) for correction of myopia. Materials and methods: A prospective, consecutive, comparative interventional case series of V4b and V4c ICL implantation done for correction of high myopia (>-6 diopter D) in patients unsuitable for laser vision correction. The outcome measures that were evaluated included preoperative and postoperative uncorrected distant visual acuity (UDVA), best spectacle corrected distant visual acuity (CDVA), endothelial cell count (ECC), presence of lens opacification, intraocular pressure (IOP) and ICL vaulting. A follow-up of upto 1 year was done. A questionnaire was given at the end of follow-up period. Results: A total of 30 eyes (24.56±4.8 years) underwent V4b ICL implantation (10 non-toric, 20 toric ICL-TICL) with intraoperative peripheral iridectomy (PI) and 34 eyes (26.13±3.8 years) had implantation of V4c ICL with centraflow (12 non-toric, 22 TICL). The mean preoperative manifest spherical equivalent (MSE) was 8.98±2.8 D and 9.24±2.4 D in the V4b and V4c groups respectively which reduced to postoperative values of -0.28±1.3 D and -0.19±1.18 D respectively. The mean preoperative astigmatism was -1.8±1.2 diopter cylinder (Dcyl) and -1.9±1.6 Dcyl which respectively reduced to -0.8±0.8 Dcyl and -0.9±0.3 Dcyl. At the end of 1 year follow up, mean ECC loss was 7.6% and 7.1%, mean vault was 583.12±231.12 μ and 602±241.24μ respectively in the V4b and V4c groups. Anterior subcapsular opacities were present in 6.66% and 2.94% of eyes with V4b and V4c groups respectively. Two eyes from both V4b (10%) and V4c (8.33%) had rotation of more than 30 degrees and required re-rotation surgery done successfully. Two eyes (6.66%) with V4b ICL implantation had high postoperative IOP (>35 mm Hg) and required Nd:Yag laser iridotomy later done with successful control of IOP. The safety indices were 1.12 and 1.15 and efficacy indices were 1.5 and 1.6 in the V4b and V4c groups respectively at the end of 1 year. The most common visual complaint was glare and haloes in 24% and 27% in the two groups respectively. However, they were not annoying enough to cause visual disability. Conclusions: Both V4b and V4c Visian ICL implantations are comparable in terms of visual outcome and safety profile for correction of high myopia. However, V4c ICL offers these advantages without the requirement of an additional PI.

Introduction: Macular hole (MH) leading to central vision loss is common in the elderly. This study aimed to explore the anatomical and functional outcome of MH surgery at a tertiary eye care setting in Nepal. Methods: This retrospective, interventional case series study included patients who had undergone MH treatment with pars plana vitrectomy, membrane peeling and perfluoropropane gas (C3F8) from 2007 January to 2010 August and had completed three months of follow up. The best corrected visual acuity (BCVA) and anatomical status of MH assessed with bio-microscopy and optical coherence tomography (OCT) at six weeks, three months and at the last follow-up following surgery were recorded. Results: A total of 36 cases with the age range of 11 - 73 years and the mean age of 53.2 years (19.3 S.D) were included in the study. The mean duration of decreased vision was 11.1 months (12.1 S.D). Idiopathic macular hole comprised of 31 cases (86.1 %) and traumatic of five cases (13.9 %). The mean follow-up period was 9.4 months. The MH closed in 27 cases (75 %) at six weeks and in 28 cases (77.8%) at three months and at the last follow-up. The vision had improved in 36 % of cases, with more than 2 lines in 27.8 %, and was stable in 27.7 % of cases during the the last follow-up. The anatomical success rate was higher in the idiopathic MH (80.65 %) than in the traumatic (60 %) and visual acuity improved in 45 % of cases in the idiopathic and 20 % in the traumatic cases. Conclusions: The overall anatomic success rate was 78 % and improvement in visual acuity was seen in one -third of cases. The success rate was higher among idiopathic MH than in traumatic.

Purpose:  To find out the demographics, presentation, and outcome of surgical treatment in patients of orbital hydatid cyst. Study Design:  Interventional case series. Place and Duration of Study:  Khyber Teaching Hospital Peshawar, Pakistan from 2009 to 2019. Methods:  This study included 11 patients with orbital hydatid cyst who presented in Khyber Teaching Hospital, Peshawar. Detailed history, ocular examination and Orbital imaging (Ophthalmic B-Scan, CT scan and/or MRI) was performed. The patients underwent Orbitotomy, cyst extirpated and sent for histopathology. Albendazole was given to the patients for 12 weeks after surgery. The preoperative and postoperative data until last follow-up was analyzed. Results:  Male to Female ratio was 5:6 and the mean age of the patients was 18.17 ± 17.4 years. Mean amount of proptosis was 26.27 ± 2.05mm and visual acuity was 0.23 ± 0.33 decimal in the affected eye at presentation. Eight patients (72.8%) had Relative Afferent Pupillary Defect with swollen discs. After imaging studies, presumptive diagnosis of hydatid cyst was made. Histopathology confirmed the diagnosis of hydatid cyst in all cases. Mean proptosis at the last follow up improved to 19.04 ± 1.45mm (P value = 0.00) and visual acuity to 0.47 ± 0.22 decimals (P value = 0.048). Only one patient (9.1%) had an associated hydatid cyst in the lung. There was no recurrence until last follow-up. Conclusion:  Hydatid cyst should be considered in differential diagnosis of proptosis in patients under 20. Surgical excision followed by a course of oral Albendazole is effective for the treatment of orbital hydatid cyst. Key Words:  Orbital hydatid cyst, Proptosis, Orbitotomy.

Purpose. The black iris-lens diaphragm (ILD) can be used in the treatment of traumatic aniridia and aphakia. The aim of our study was to show postoperative functional and anatomic results and complications in a small case series. Methods. We retrospectively analyzed the files of 16 patients managed with a black ILD or a sole iris diaphragm in the period 1994–2007. Four of them were female and 12 were male. The mean age of the group was 50±17 years. At the time of the implantation, all of the eyes had already undergone primary surgical repair. Results. The preoperative best-corrected visual acuity in half of the patients was ≥0.1 and remained stable after the first postoperative year. During the follow-up years, one eye developed a subluxation of the implant and one eye an anterior chamber hemorrhage. At the same time, out of 8 eyes carrying a silicone tamponade in the vitreous cavity, silicone oil entered the anterior chamber in 3 cases. In one case, enucleation was undertaken due to phthisis. Conclusions. In the case of severely traumatized eyes with aniridia and aphakia, the implantation of a black ILD can have a positive effect on functional and anatomic stabilization.

Aim: To evaluate the effect of phacoemulsification with intraocular lens implantation in eyes with pre-existing trabeculectomy.Methods: This prospective single-center clinical study evaluated intraocular pressure in 60 eyes of 60 patients who underwent phacoemulsification and implantation of a foldable intraocular lens after a previous successful trabeculectomy. Patients who had a trabeculectomy more than one year prior to the study were included. Intraocular pressure, number of antiglaucoma medications, bleb appearance, and visual acuity were recorded preoperatively, and at each follow-up examination and 12 months after phacoemulsification.Results: The mean intraocular pressure before phacoemulsification was 12.42 mmHg (SD, 4.60 mmHg), which increased to 14.98 mmHg (SD, 4.18 mmHg), 14.47 mmHg (SD, 3.58 mmHg), 15.44 mmHg (SD, 3.60 mmHg), and 15.71 mmHg (SD, 3.47 mmHg) after one, three, six, and 12 months, respectively. At each follow-up visit, the mean IOP was significantly higher than the preoperative value (p < 0.001, p = 0.015, p ≤ 0.001, and p = 0.001 at month one, three, six, and 12, respectively). The mean preoperative best-corrected visual acuity was 0.98 logMAR (SD, 0.44 logMAR) and the mean postoperative best-corrected visual acuity at 12 months was 0.20 logMAR (SD, 0.21 logMAR) [p = 0.0001]. The mean preoperative number of antiglaucoma medications used was 0.57 (SD, 0.63), which increased to 0.65 (SD, 0.63 ), 0.70 (SD, 0.72 ) 0.68, (SD, 0.70), and 0.67 (SD, 0.77 ) at one, three, six, and 12 months, respectively, but there were no statistically significant differences. Bleb size decreased clinically after phacoemulsification. Nineteen of 60 eyes (32%) developed fibrosis of bleb with decreased bleb size.Conclusion: Phacoemulsification with intraocular lens implantation significantly increased intraocular pressure and increased the number of antiglaucoma medications in eyes with pre-existing functioning filtering blebs.

Purpose. One of the most difficult refractory glaucomas is the neovascular type (NVG), and its association with dense cataract adds to this difficulty. This study aimed to provide results of the triple surgical procedure for such conditions. Methods. 12 eyes of 12 patients with NVG and dense cataract were included in this case series study. The mean age of patients was 57.25 ± 5.9 years. The mean preoperative intraocular pressure (IOP) was 47.25 ± 4.04 mmHg with maximum antiglaucoma therapy. The mean best corrected distant visual acuity (BCDVA) in LogMAR was 2.13 ± 0.38. All patients received intravitreal injection of 1.25 mg (0.05 ml) bevacizumab followed by phacoemulsification, pars plana vitrectomy (PPV) including panretinal photocoagulation (PRP), and trabeculectomy with mitomycin C (MMC). Mean IOP and BCDVA changes were the main outcome results of this study. Results. The follow-up period was 2 years. The mean BCDVA was improved to 1.22 ± 0.35, 1.13 ± 0.34, 1.12 ± 0.37, 1.06 ± 0.38, and 1.01 ± 0.37 at 1, 3, 6, 12, and 24 months, respectively, after this procedure. This improvement was statistically significant when compared with preoperative BCDVA (P<0.0001). The mean postoperative IOP was dropped to 20.08 ± 4.1, 17.08 ± 2.1, 17.17 ± 5, 15.75 ± 4.7, and 16.17 ± 6.1 mmHg, respectively. At the last follow-up, the mean IOP was statistically significantly lower than preoperative IOP (P<0.0001) at the previously mentioned time points. The success rate was complete in 90.9% of eyes and qualified in 100% of eyes. Iris and angle neovascularization had regressed significantly in all patients, and no serious complications occurred during the follow-up period. Conclusions. This triple surgery can safely improve patients with NVG and dense cataract regarding BCDVA and IOP control. This trial is registered with NCT04143620.

Purpose: To describe the feasibility and efficacy of performing single-pass four-throw pupilloplasty for secondary angle-closure glaucoma post silicon oil tamponade. Methods: The procedure was performed in five eyes of five patients. All the cases underwent silicon oil removal with single-pass four-throw pupilloplasty. Single-pass four-throw procedure involves a single pass of needle through the iris tissue that is to be apposed followed by taking four throws by passing the suture end through the loop that is withdrawn from the anterior chamber as in a modified Siepser’s slip-knot technique. Both the suture ends are pulled and this leads to sliding of the loop into the anterior chamber. Surgical pupilloplasty stretches the peripheral iris tissue and helps in breaking the peripheral anterior synechia. Intraoperative gonioscopy and anterior segment optical coherence tomography were performed in all the cases. Results: Intraoperative gonioscopy and anterior segment optical coherence tomography demonstrated opening of the anterior chamber angles with breakage of peripheral anterior synechia. The mean preoperative and postoperative best-corrected visual acuity in logarithm of minimum angle of resolution was 1.24 ± 0.23 and 0.56 ± 0.18, respectively (p < 0.001). The mean preoperative and postoperative intraocular pressure was 38.2 ± 4.97 and 13.0 ± 2.35 mm Hg, respectively. There was a significant decrease in intraocular pressure and marked improvement in visual acuity in all the cases. Conclusion: Surgical pupilloplasty helps to relieve the post-silicon oil-induced secondary angle-closure glaucoma by breaking peripheral anterior synechia and significantly opening the anterior chamber angles.

Background: This study was aimed at assessing clinical and radiographic outcomes of the Minimally Invasive Intramedullary Nail Device (MIIND) to correct moderate to severe hallux valgus (HV) and the long-term persistence of its effects. Methods: This case series study involved 100 patients, 84 women and 16 men (mean age, 59 years), who underwent the MIIND procedure with a mean follow-up of 97 months. Assessment was performed preoperatively, postoperatively, at 6 and 12 months, and at last follow-up. Clinical outcomes were evaluated with American Orthopaedic Foot & Ankle Society (AOFAS) scores, visual analog scale (VAS), and patient satisfaction. Intermetatarsal angle (IMA), metatarsophalangeal hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), and tibial sesamoid position were assessed. Statistical analysis was performed. Results: The mean AOFAS score improved from 57.9 to 90.5 points, VAS scale was 1.5 ± 2.0, and patients’ satisfaction was 8.7 ± 1.4. The mean correction of the HVA and IMA showed a significant correction; however, the effect of time was not statistically significant on DMAA. Sex ( P = .047), severity ( P = .050), associated procedures ( P = .000), and preoperative angle ( P = .000) showed significant association with HVA correction and its persistence over time. Age was not statistically significant. Complications were 9 cases of superficial wound infection and 6 recurrences. Conclusions: The MIIND technique proved a viable procedure to correct moderate to severe HV with a low rate of complications and recurrence, producing significant correction of most radiographic parameters assessed and their persistence, even at long term. Level of Evidence: Level IV, case series study.

The purpose of this study was to report our experience of partial capitate shortening in seven patients with a median 38 months follow-up. Staging was made by the Lichtman classification system and stage II and III-A patients were included in the study. The mean age was 34 years (range 22–52). Patients were assessed for pain, range of motion, grip and pinch strength, and satisfaction was recorded using a scale between 0 and 4. All these parameters showed improvement after surgery. The Lichtman stage, lunate height index and carpal height index were determined radiographically. Magnetic resonance images of the wrist were studied for lunate revascularization at the final follow-up and occurred in all patients. According to our study, partial capitate shortening seems an effective treatment for Lichtman stage II and III-A patients. Level IV case series study.
