Scleral Fixated Intraocular Lens

Introduction: Scleral fixated intraocular lens(SFIOL) implantation to correct aphakia offers superior visual rehabilitation in comparison to aphakic spectacles or contact lens. This study was done to evaluate a simplified technique of scleral fixation of posterior chamber intra-ocular lens (IOL) in terms of visual outcome and complications.Methods: This was a prospective study enrolling 23 eyes of 23 patients who underwent anterior vitrectomy followed by ab-externo sclera fixation of posterior chamber IOL using 10.0 polypropylene sutures from January 2016 to February 2017 in Nepal Eye Hospital.Scleral flap was made at 3 and 9'o clock meridian to cover the knots which prevent erosion of the knots through conjunctiva.  Main outcome measures were post-operative best corrected visual acuity and post-operative complications.Result: Best corrected visual acuity were 6/6 - 6/18 in 86.9% (n=20), 6/24 - 6/60 in 8.7% (n=2) and worse than 6/60 in 4.3% (n=1)at six months followup. The mean spherical equivalent before surgery was +10.60 diopter and -1.14 diopter post-surgery. The common indicationsfor scleral fixated intraocular lens weretrauma in 60.86% (n=14), surgical aphakia in21.73% (n=5), spontaneous posterior dislocation of lens in 13.0% (n=3) and subluxated intraocular lens in 4.34% (n=1). The common complications were astigmatism in 91.30% (n=21), decentered IOL in 4.34% (n=1) and uveitis in 4.35% (n=1).Conclusion: Ab-externosclerated fixated intraocular lens is a safe and effective method for visual rehabilitation with low post-operative risk.

To evaluate post operative visual outcome and complications of retro-pupillary iris fixated Intracoular lens (IOL) in aphakia. This is a prospective interventional case study conducted at our tertiary eye care centre from March 2018 to February 2019 All monocular aphakias secondary to any cause with no capsular support, good iris diaphragm support and BCVA of better than 6/60 were included. Patients who required combined procedures like trabeculectomy and retinal procedure were excluded. Patients with poor endothelial count/ corneal decompensation, any posterior segment pathologies, pre existing glaucoma and any form of uveitis were also excluded from the study. Pre operative visual acuity, slit lamp examination and fundus examination were carried out. Anterior vitrectomy and retropupillary fixation of iris claw lens were done. The primary outcome was to assess the post operative visual acuity and secondary outcome was to analyse post operative complications at various intervals up to 6 months after surgery. Our study comprised of thirty eyes of 30 aphakic patients. RPIFIOL was inserted as primary intraocular lens in 18 patients (%) and secondary intraocular lens in 12 patients(%). Baseline best corrected visual acuity was 0.831±0.66 logMAR. Four patients had light perception at baseline. The mean best corrected visual acuity was 0.77±0.35 logMAR at month 1, 0.64±0.36logmAR at month 3 and 0.53±0.33logmAR at month 6 respectively. Mean intraocular pressure at baseline was 16mmHg. Mean intraocular pressure at month 1, 3 and 6 were 17mmHg, 16mmHg, and 16mmHg. Among the complications, twelve eyes (40%) had significant ovalisation of pupil at post operative month 1 which persisted at month 6, two eyes(6.66%) had transient ocular hypertension (OHT), and none of the eyes progressed to glaucoma. Choroidal detachment was noted in 2 eyes (6.66%), CME in 3 eyes (9.99%), 1 eye (3.33%) had retinal detachment and 2 eyes (6.66%) had one haptic disenclavation. Among the complications, ovalisation of pupil was the most common observed one. Retro-pupillary Iris fixated IOL is an effective, safe and simple procedure for management of aphakia in eyes with no posterior capsular support.

Objective To present the surgical outcome of posterior chamber intraocular lens scleral fixation using a 27-gauge trocar-assisted transconjunctival sutureless technique in aphakic patients due to cataract surgery complications with inadequate capsular support. Methods Six consecutive patients with aphakia due to cataract surgery complications with inadequate capsular bag support were operated by two surgeons. Intraocular lens scleral fixation was performed with a 27-gauge trocar-assisted transconjunctival sutureless technique. Patients were followed-up for 12 months. Preoperative and postoperative best-corrected visual acuities were assessed with Early Treatment Diabetic Retinopathy Study charts and expressed in decimals. Results All patients showed statistically significant best-corrected visual acuity improvement and excellent anatomic results. Mean preoperative best-corrected visual acuity was 0.17 (range of 0.1–0.2). Mean postoperative best-corrected visual acuity was 0.84 (range of 0.63–1.00). Mean initial spherical equivalent refractive error was +11.85 (range of +9.00 to +15.00). Mean final spherical equivalent refractive error was –0.25 (range of –1.25 to +2.25). There were no postoperative complications during the whole follow-up. Conclusion Fixation of a posterior chamber intraocular lens using a 27-gauge trocar-assisted transconjunctival sutureless intrascleral technique is an excellent option for aphakic patients secondary to cataract surgery complications with inadequate capsular support.

Aim: To assess the complications and visual outcomes associated with cataract surgery in camp patients operated at a tertiary centre. Materials and methods: In a retrospective study, 206 outreach camp patients had undergone cataract surgeries with posterior chamber intraocular lens implantation under peribulbar anesthesia over a period of 6 months. Post-operative complications on Day 1 were graded as per Oxford Cataract Treatment and Evaluation Team (OCTET) definitions. One month postoperative complications, best corrected visual acuity and refractive errors were assessed. Results: 206 eyes underwent cataract extraction with PCIOL implantation. Small incision cataract surgery (SICS) was the commonest method (78.6%) used. The most common first post-operative day complication was mild iridocyclitis (26.2%). The complications were based on OCTET definitions, and showed that 33 % had Grade I and 3.4 % had Grade II complications. The major post-operative complication after 4 weeks of surgery was posterior capsular opacity. 89.8 % of the eyes had a 4 week-post-operative best corrected visual acuity of e” 6/24. The commonest refractive error was myopia with against the rule astigmatism, seen in 86 out of 150 cases. Conclusion: High quality cataract surgery with a low rate of intra-operative complications and good visual outcome can be attained in camp patients operated in the base hospitals, thus justifying more similar screening camps to clear the vast cataract backlog.

Purpose: The aim of this article is to describe a novel surgical technique for sutureless scleral fixation of an intraocular lens using the newly developed FIL SSF Carlevale IOL (Soleko, Italy). Methods: Four eyes of four patients with poor capsular support were recruited to our study, three resulting from intraocular lens subluxation and one case resulting from traumatic cataract. A novel sutureless sclera-fixated intraocular lens was implanted into the posterior chamber of each eye with sclerocorneal plugs fixating the lens to the wall of the eye. Results: Mean age of patients was 52 ± 16 years, ranging from 35 to 70 years. Mean follow-up was 6.50 ± 1.29 months (range: 5–7 months). Mean preoperative best-corrected visual acuity was 0.50 ± 0.33 logMAR (range: 1–0.3 logMAR). Postoperative best-corrected visual acuity improved to 0.08 ± 0.08 logMAR (range: 0.2–0 logMAR). There was no significant change in the mean intraocular pressure and there were no postoperative complications, such as iatrogenic distortion or breakage of the intraocular lens haptic, intraocular lens decentration, endophthalmitis, or retinal detachment. Discussion: To the best of our knowledge, this is the first report of outcomes using the novel sutureless sclera-fixated FIL SSF Carlevale IOL. This new surgical technique offers a simplified and effective approach for sutureless scleral intraocular lens fixation with good refractive outcomes.

To analyze the visual outcome in patients with pseudoexfoliation and to know the surgical parameters to cogitate in patients with pseudoexfoliation syndrome. An Observational study which was conducted in the Ophthalmology department in a tertiary care hospital in a rural area from June 2019 to December 2019. A total of 52 eyes of 52 patients aged 40 years and above, of either sex, clinically diagnosed with senile cataract and associated with pseudoexfoliation were enrolled in the study. After assessing best corrected visual acuity (BCVA), a detailed anterior and posterior segment examination was performed along with lacrimal sac syringing, manual keratometry, contact A-scan biometry and intraocular lens (IOL) power was calculated. All patients underwent manual small incision cataract surgery under peribulbar anaesthesia and intraocular lens was implanted. Intraoperative complications were noted during the surgery and was reported .Best corrected visual acuity was recorded on day 1, at 1week and at 1 month of follow up. Out of 52eyes of 52 patients, 29 were females (55.76%) and 38 eyes (73.07%) exhibited bilateral involvement. Distribution of the PXF material in various ocular structures was observed and majority of them (36.53%) had PXF material equally in iris, pupillary margin and lens. Based on the morphology of cataract associated with psudoexfoliation, nuclear cataract was the most commonly observed in 16 eyes (30.76%) and 42 eyes (80.76%) had moderate pupillary dilatation. The intraoperative difficulties observed during cataract surgery was poor pupillary dilatation which was managed by controlled sphincterotomy during the surgery in 3 eyes (5.76%), Iridiodialysis, rhexis extension, zonular dialysis each in 1 eye and posterior capsular rent in 2 eyes. Around 92.30% of the total study population achieved post-operative BCVA of 6/12 or better at 1month of follow up. Decreased visual acuity was noted in 2 (3.84%) eyes due to persistent corneal edema, one eye (1.92%) had posterior capsular opacification and one eye (1.92%) had cystoid macular edema. This study concludes that with careful preoperative assessment and necessary intraoperative precautions, good visual outcome can be achieved in patients with cataract with pseudoexfoliation.

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.

Introduction: This study was conducted to report the refractive and visual outcome after Scleral Fixated Intraocular Lens (SFIOL) implantation in children with nontraumatic ectopia lentis. Methods: Retrospective review of the medical records of 25 eyes of 15 patients who underwent SFIOL implantation in children with non-traumatic ectopia lentis. Results: The mean best corrected visual acuity (BCVA) before SFIOL implantation was 1.07 ± 0.9 logMar units [median: 0.9, Interquartile range (ΙQR): 0.415 to 1.555] which improved to 0.41 ± 0.33 logMar units (median: 0.22, ΙQR: 0.180 to 1.555) at two months postoperative follow up. In phakic group, the mean spherical refraction preoperatively was -12.04 ± 7.82 DS (dioptre sphere) (IQR: +16 to -5.875) and postoperatively was +0.93 ± 2.67DS (IQR: -0.375 to +2). In aphakic group, the mean spherical refraction preoperatively was +12.22 ± 2.05 DS and postoperatively was +1.2 ± 1.9 DS. The mean total astigmatism preoperatively was -6.44 ± 4.95 DC (dioptre cylinder) (median: 6, IQR: -10.50 to +2) and postoperatively was -1.47 ± 0.98 DC (median: -1.5, IQR: -2 to - 0.625 ). The mean IOL induced astigmatism was -1.01 ± 0.95 DC (median -0.75, IQR: -1.33 to - 0.25). The spherical refractive equivalent was within 2 Diopter (D) of the target refraction calculated preoperatively in 20 eyes and in five eyes it was more than 2 D. Conclusion: SFIOL implantation is associated with good visual outcome with a significant improvement in the refractive error. However, a longer follow up is required to assess the change of refraction and the stability of the SFIOL.

Visual rehabilitation in aphakia has been a challenge with a wide variety of surgical options available for ophthalmologist. We report the visual outcome with retropupillary iris claw lens secondary to intra operative complications and secondary implantation in aphakia. An interventional study on 4 eyes of 4 patients was conducted. Preoperative visual acuity, slit lamp examination and fundus examination were carried out. Anterior vitrectomy and retropupillary fixation of iris claw lens were done. The primary outcome measure was best-corrected visual acuity and secondary postoperative complication was recorded at various intervals. All patients had visual acuity of ≥6/18 postoperatively. Sutureless retropupillary iris claw intraocular lens implantation is a good alternative of scleral-fixated intraocular lenses in aphakic patients.
