Abstract Background To evaluate application of AS-OCT in PCO severity assessment and analyse relationship between PCO severity and IOL characters. Methods PCO patients were prospectively recruited. Cross-sectional images of the anterior segment at horizontal and vertical medians were acquired with AS-OCT. The area of the IOL-PC (posterior capsular) space and PCO severity (area, thickness and density at 3 mm and 5 mm IOL optic regions) were measured. The relationship between visual acuity and PCO severity, comparisons of PCO severity and IOL-PC space using varied IOL designs were analysed. Results One hundred PCO eyes were enrolled. IOL-PC space and PCO thickness and area was positively correlated with axial length. The cut-off level of visual acuity: was 0.52 Log MAR. Visual acuity were positively correlated with PCO area and thickness when visual acuity was ≤ 0.52 Log MAR. 3-piece C haptic IOL showed a smaller PCO area and thickness than the 1-piece 3 haptic IOL and 1-piece 4 haptic IOL. PCO area and thickness values for an IOL with a diameter ≤ 11.0 mm were greater than for an IOL with a diameter of 12.5 mm. The differences were statistically significant. PCO area and thickness increased when IOL haptic angulation increased (from 0 to 12 degrees). Conclusions In PCO eyes, cut-off level of visual acuity was 0.52 Log MAR. With more severe PCO, visual acuity maybe not enough to describe the visual function impairment. PCO severity and IOL-PC space was significantly correlated with axial length and IOL design and material.

Visual Disturbances

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.

Case Series Study

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.
