Abstract
The lens is a transparent biconvex structure in the eye that helps to refract light to focus on the retina. Cataract is opacity of lens or capsule which is either developmental or acquired. To assess the retinal nerve fibre layer (RNFL) thickness, signal strength before and after phacoemulsification cataract surgery. To assess the effect of media opacity like cataract on OCT measurements. Methods: A hospital based Prospective, Single Centre study was carried out Patients attending the Ophthalmology OPD who gave a written informed consent to be a part of this study at tertiary care Centre. The study was conducted from August 2022 to August 2023. Results: The mean age at presentation was 59.50 ±7.81 years. 89 (44.5%) are females and 111(55.5%) are male. 14 (7%) were having cortical cataract, 47 (23.5%) nuclear cataract only, 23 (11.5%) had posterior sub capsular cataract only and 116 (58%) of the eyes had both nuclear and posterior sub capsular cataract together. Mean Signal strength pre and post‐surgery is 4.8±1.24 and 7.8 ±0.79 respectively. Mean RNFL thickness increased from 75.62±13.8μm to 92.01±12.94μm post operatively. There is statistically significant increase in RNFL thickness and signal strength in both glaucoma and non‐glaucoma patient‘s. In conclusion, our data suggest that the presence of lenticular opacity significantly affects RNFL thickness measurements, signal strength using Cirrus OCT. In clinical practice, an increase in RNFL thickness, signal strength can be expected after cataract surgery and we recommend obtaining fresh OCT images after cataract surgery to define a new baseline for patients who need glaucoma follow‐up.
