Objective. To evaluate and compare the impact of two sharp-edge optic foldable intraocular lenses (IOLs) of similar design made from different material (hydrophilic acrylic or hydrophobic acrylic) on visual function, anterior and posterior capsule opacification at one-year follow-up after cataract phacoemulsification. Material and methods. Seventy-two eyes of 72 patients scheduled for cataract surgery were included in a prospective clinical study. Two foldable sharp-edge optic posterior chamber acrylic IOLs of similar design were used. Thirty-nine eyes of 39 patients received a single-piece hydrophilic acrylic (PC 511, Ophtec) IOL and 33 eyes of 33 patients – single-piece hydrophobic acrylic (AcrySof, SA60AT, Alcon) IOL. Visual acuity, anterior capsule opacification (ACO), capsulorrhexis/optic overlapping, and posterior capsule opacification (PCO) were evaluated. The intensity of ACO was assessed subjectively. PCO values in the entire IOL optic area and in the central 3-mm optic zone were assessed using a photographic image analysis system (EPCO 2000). The patients were examined at one year postoperatively. Results. There were no significant differences in best-corrected visual acuity and capsulorrhexis/optic overlapping between IOL types at 1-year follow-up after surgery. In the single-piece hydrophilic acrylic IOL group, the grade of ACO density was significantly higher in capsulorrhexis rim area (1.56±0.71 and 1.00±0.75) and in the capsule/optic area (1.62±0.67 and 1.00±0.75) (P<0.05). PCO values of the entire IOL optic area (0.12±0.13 and 0.024±0.02) as well as in the central 3-mm optic zone (0.06±0.11 and 0.001±0.003) was significantly higher in the single-piece hydrophilic acrylic IOL group one year postoperatively (P<0.05). In 33.3% of cases of the single-piece hydrophilic acrylic IOL group, contraction of haptics to IOL optics was present one year postoperatively, which was not present in any case of the single-piece hydrophobic acrylic IOL group. Conclusions. One-year follow-up after cataract surgery has shown a significant difference in ACO and PCO development comparing single-piece hydrophilic acrylic and single-piece hydrophobic acrylic intraocular lenses. The effect of hydrophobic acrylic foldable lenses on preventing anterior and posterior capsule opacification is mainly a result of the acrylic hydrophobic biomaterial.

Objective. To evaluate intraocular scattering in eyes with posterior capsule opacification by means of an objective scatter index (OSI) obtained from double-pass images of optical quality assessment system (OQAS TM II) and to determine the indication for laser capsulotomy when patients report visual disturbances without decreased visual acuity. Methods. In this prospective, observational, and nonconsecutive case series study, a total of 32 eyes of 29 patients are diagnosed with posterior capsule opacification after age-associated cataract were analyzed. Patient examination included age, the period after cataract surgery, logMAR best corrected visual acuity (BCVA), and OSI. Results. We found a significant decrease in the BCVA and increase in the OSI with the development of posterior capsule opacification. The decrease of BCVA was statistically correlated with the increase of OSI (r=0.812, P<0.01). In patients who reported visual disturbances without decreased visual acuity, OSI decreased to <1.3 and subjective symptoms were resolved in all cases although there was no significant improvement in visual acuity after laser capsulotomy. Conclusions. The results of our study showed that OSI is also a useful parameter for objectively evaluating posterior capsule opacification. OSI may help predict laser capsulotomy in patients who report visual disturbances without decreased visual acuity.

OBJECTIVES: To determine the frequency of complications following cataract surgery in diabetic patients admitted in the ophthalmology unit. METHODOLOGY: A prospective descriptive interventional case series study was conducted after approval of the ethical committee, from June 2017-June 2020 at the Ophthalmology department MTI-MMC. A total of 129 patients from either gender were enrolled in study. All the study patients went through detailed history and complete ocular examination. After necessary investigations, surgical procedure was carried out. Results were analyzed through the SPSS-24 version. RESULTS: Out of the total 129 eyes of the diabetic patients, fifty-nine (45.7%) were males and seventy (54.3%) were females with a ratio of 1:1.2. Uveitis leads the chart in complications found in twenty (15.50%) eyes while PODR being the least common found in only ten (7.75%) eyes. Worse visual acuity was observed in fourteen (10.85%) eyes. Striate keratopathy and posterior capsule opacification were found in sixteen (12.40%) and fifteen (11.62%) eyes respectively. Among the patients, 15.7% were having more than one complication during follow-up visits and eighty-eight (68.2%) eyes were found to have none complication. The age group 51-60 years observed frequent complications as compared to other groups. Similarly female gender (38.57%) has frequent complications as compared to males (2.7%). CONCLUSION: The study concludes Uveitis as the most common complication observed in 15.50% 0f the eyes while worse visual acuity (10.85%) and progression of diabetic retinopathy (7.75%) being the least common. Striate keratopathy was found in 12.40% while posterior capsule opacification in 11.62% of the eyes.
