Currently, posterior chamber intraocular lenses (IOLs) correct totally or partially spherical aberrations. In this article we present the visual results of a prospective multicentre study evaluating the Micro AY IOL correcting 0.11μm of spherical aberration, which is a good compromise between optimal vision and a consistent depth of focus. We evaluated 124 eyes that were operated on using bi-manual micro-cataract surgery (BiMICS: 75%) or co-axial micro-cataract surgery (CoMICS: 25%) phacoemulsification with insertion of a Micro AY IOL through a 1.8–2.2mm incision. Mean post-operative best corrected visual acuity was 0.97±0.25; pre-operative spherical aberrations were +0.24±0.13μm, and reached +0.10±0.11μm post-operatively. There were no complications due to the lens, and photopic contrast sensitivity reached high levels.

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.

To evaluate changes in macular thickness via-a-vis visual acuity post uncomplicated manual small incision cataract surgery (MSICS) & phacoemulsification surgery Prospective clinical study on 160 patients of uncomplicated immature senile cataract, aged 40-70yrs, patients were randomised into two groups, MSICS & phacoemulsification, by simple 1:1 randomization, who underwent uncomplicated cataract surgery with posterior chamber intraocular lens (PCIOL). Post-operatively, the patients were evaluated for best corrected visual acuity (BCVA) and changes in macular thickness by optical coherence tomography (OCT) at post-op Day 1, 7, 21, 48, and 12 weeks. Paired t-test was used for comparison across follow up. : At 12 weeks post-operative, mean logMAR BCVA was 0.01±0.02 for MSICS group and 0±0.02 for Phacoemulsification group. Macular thickness was not statistically significant (p=0.342) between MSICS group (219.19±17.88µm) and Phacoemlusification group (215.61±16.21µm), at the end of 12 weeks post-operative. Clinically significant macular oedema was not diagnosed in any of the patients at the follow-ups.: Both procedures achieved good post-operative Best Corrected visual acuity without significant differences in BCVA between both the groups at the end of 12 weeks.

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. To assess visual results and complications of a modified technique of posterior chamber intraocular lenses (PC IOLs) in aphakic eyes without scleral flaps.Methods. Modified one-haptic scleral fixation was performed in one eye each of 25 patients with aphakia and insufficient capsule support. Follow-up period was six months. Outcome measures included best-corrected visual acuity, intraocular pressure (IOP), and postoperative complications.Results. The study included 15 males and 10 females. The preoperative best-corrected visual acuity (BCVA) ranged from 5/60 to 6/9. The operation time ranged from 25 to 45 minutes (mean 35.25 ± 5.34 min). Anterior vitrectomy was performed in 12 cases (48%). There was no major IOL decentration. The final BCVA ranged from 6/36 to 6/9. Seven cases (28%) showed postoperative glaucoma, five cases (20%) had temporary hypotony, and hyphema in 2 eyes (8%). No cases of suture erosion, postoperative endophthalmitis, retinal detachment, or IOL dislocation were detected.Conclusion. This technique of one-haptic scleral fixation of posterior chamber IOLs is a good choice in presence of insufficient capsule support. It reduces the operation time, achieves the IOL stability, and minimizes postoperative suture-related complications.

Dry Eye Symptoms

Introduction. Dry eye syndrome has become a common problem after ocular surgeries with a significant impact on the quality of life. Many patients, who have undergone cataract surgery, postop?eratively developed dry eye symptoms. Dry eye syndrome is one of the risk factors associated with cataract surgery. Material and Methods. The prospective study included 80 patients. We recorded the self-reported dry eye symptoms, the values of Schirmer test, tear breakup time, and best corrected visual acuity preoperatively, as well as 7 days and 1 month after the surgery. Results. A total of 80 patients were included in the study, 45 (56.2%) females and 35 (43.8%) males. The mean age of patients was 61.5 years (SD ? 6.2, range 57 - 70 years). The best corrected visual acuity at the time of surgery was 0.4 or less in 70 patients (87.5%). Most patients reported a significant improvement in visual acuity after surgery; 68 (85%) eyes achieved a best corrected visual acuity of 0.5 or higher (median 0.7; range 0.5 - 1.0). The mean tear breaking time in cata?ract patients before surgery was 12.4 sec, 7 days after the surgery it was 8.2 sec (p < 0.05) and 1 moth after the surgery 11.1 sec. The majority of patients had mild (47.5%) and moderate (33.75%) Schirmer test values. Dry eye with wetting < 5 mm after 5 minutes was found in 16.2% of patients before cataract surgery; 7 days after the surgery (p < 0.05) it was found in 23.75% of patients and one month after surgery 11.1 sec. A foreign body sensation and watery eye were the most reported symptoms before cataract surgery. Seven days after the surgery foreign body sensation was present in 48.75% and watery eyes in 40% of patients. Conclusion. Significant increase in dry eye symptoms after cataract surgery was found with increasing age. Self reported dry eye problems are more common in patients with lower Schirmer test and best corrected visual acu?ity values before cataract surgery. Patients with concomitant dry eye disease require preoperative and postoperative treatment of dry eye to prevent aggravation of the existing symptoms that may affect the visual outcome after cataract surgery.

Abstract Background: malignant glaucoma after cataract surgery is still one of the serious complications, if not handled properly，it may lead to serious consequences. It is notoriously difficult to treat. 25G vitrectomy was performed to evaluate the safety and efficacy for the treatment of malignant glaucoma in pseudophakia. Methods: This is a retrospective, comparative case series study. A total of 20 eyes of 20 patients with malignant glaucoma after phacoemulsification were analyzed retrospectively in The First Affiliated Hospital Of Anhui Medical University from May 2015 to January 2018. All Medical Data including the best corrected visual acuity (BCVA), Change of intraocular pressure (IOP), the length of eye axis, and the depth of anterior chamber were recorded. SPSS 17.0 statistical software was used for analysis .Before surgery, the best corrected visual acuity (BCVA) was 1.8±0.6. The intraocular pressure was between 18-57mmHg, with an average of 35.2±10.4mmHg.The depth of anterior chamber was between 0.9-1.9mm, with an average of 1.3±0.2mm.The length of eye axis was 19.7-22.5mm,with an average of 20.6±0.5mm.All the patients were accomplished with 25G vitrectomy. Besides, anterior chamber inflammatory reaction and other complications were also observed postoperation. Results: The patients were followed up for 6-12 months with an average of 9 months. BCVA at the last follow up improved to 0.8±0.1, and there was significant difference compared to that before operation (P<0.01).IOP was from 12-19mmHg, an average of 16.1±2.5mmHg, there was significant difference compared to that before operation (t=7.6, p<0.01).Only one patient occurred low IOP (6mmHg) after surgery, IOP returned to normal level (14mmHg) after conservative treatment. No serious complications including corneal endothelium decompensation, intraocular lens (IOL) capture, intraocular hemorrhage, endophthalmitis and uncontrolled IOP were observed. Conclusions: 25G minimally invasive vitrectomy can treat malignant glaucoma after cataract surgery safely and effectively

Background:The purpose of the study was to identify macular edema after cataract surgery in eyes with and without pseudoexfoliation syndrome. The study was a post-hoc analysis of a randomized, double-blind, prospective single-center study. Patients were enrolled between January 2016 and October 2016 as per the national guidelines for the management of cataract in the Department of Ophthalmology, Kymenlaakso Central Hospital, Kotka, Finland.Methods:One hundred and fifty-six eyes of 149 patients undergoing routine cataract surgery. Postoperatively anti-inflammatory medication was either dexamethasone (N = 78) or diclofenac (N = 78). Spectral domain optical coherence tomography imaging and laser flare meter measurement of the anterior chamber were conducted before surgery and at the control visit 28 days postoperatively.Results:Baseline variables were comparable between eyes with pseudoexfoliation syndrome (N = 32) and those without (N = 124), except for intraocular pressure ( P = 0.002) and glaucoma medication ( P < 0.001). In patients having pseudoexfoliation syndrome, central retinal thickness increase (mean ± standard error of the mean) was 63.3 ± 35.5 μm for dexamethasone and 17.6 ± 5.8 μm for diclofenac, compared to 28.9 ± 8.0 μm ( P = NS) and 6.9 ± 1.3 μm ( P = 0.014) in eyes without pseudoexfoliation syndrome, respectively. Aqueous flare at 28 days was 25.8 ± 5.4 pu/ms for patients with pseudoexfoliation syndrome and 18.3 ± 1.8 pu/ms for those without ( P = 0.030). Best corrected visual acuity gain and best corrected visual acuity at 28 days were less in patients having pseudoexfoliation syndrome compared to those without (0.39 ± 0.07 vs 0.59 ± 0.03 decimals, P = 0.007; and 0.77 ± 0.06 vs 0.92 ± 0.03 decimals, P = 0.008, respectively).Conclusion:Eyes with pseudoexfoliation syndrome may be predisposed to an increased aqueous flare and macular edema after cataract surgery. This study outlines the need to determine the optimal anti-inflammatory medication after cataract surgery in patients with pseudoexfoliation syndrome.

Purpose: To report the safety and efficacy of subthreshold micropulse yellow laser of 577 nm for a complex case of refractory pseudophakic cystoid macular edema. Methods: A retrospective chart review of an interventional case report of three subthreshold micropulse yellow laser interventions for refractory pseudophakic cystoid macular edema. Patient: A 77-year-old healthy female underwent pseudoexfoliative cataract surgery complicated by posterior capsule rupture and sulcus intraocular lens implantation. After 3 months, she required a scleral fixation of the same lens, due to a lack of capsular support and decentration of the intraocular lens. One month later, she experienced a severe pseudophakic cystoid macular edema (foveal thickness of 399 µm and best-corrected visual acuity of 20/80 Snellen). The condition was refractory to conventional treatments prior to subthreshold micropulse yellow laser interventions, including non-steroidal anti-inflammatory eye drops, topical steroids, oral indomethacin and three sub-Tenon’s triamcinolone injections, attempted over a 14-month period. Results: Subthreshold micropulse yellow laser treatment was performed and immediate resolution was achieved and maintained for 2 months. Two cases of edema relapse were observed at 3 months from initial laser treatment and again at 4 months from the second laser treatment. Final patient’s follow-up at 6 months from the third laser treatment evidenced the absence of edema, improved visual acuity (foveal thickness of 265 µm/best-corrected visual acuity of 20/30 Snellen) and the absence of complications. Conclusions: Subthreshold micropulse yellow laser seems to be a safe and effective treatment for short-term resolution of refractory pseudophakic cystoid macular edema after complicated cataract surgery and represents a useful alternative to expensive and invasive therapies. A trend towards a longer duration of edema resolution with every subthreshold micropulse yellow laser repetition was observed.
