Abstract

The purpose of this study is to comparatively evaluate the morphology of cataract, intraoperative and postoperative complications (IPC), and surgical outcomes of phacoemulsification in post 23G vitrectomized eyes in silicone oil versus air/gas group. This prospective interventional clinical study took place in the Dr. RP Centre for Ophthalmic Sciences, AIIMS, New Delhi, India. Eighty-nine eyes of 89 consecutive vitrectomized patients with cataract were included. All underwent phacoemulsification and evaluated for cataract morphology, surgical difficulties, IPC, visual acuity, and specular count. Mean age of patients was 50.24 ± 15.19 years. There were 65 males and 24 females and 48 eyes in silicone oil group and 41 in air/gas group. Combination type was the commonest morphology seen in both silicone oil (52.08 %) and air/gas group (70.33 %) followed by posterior subcapsular cataract (PSC) in 31.25 % silicone group and 12.2 % air/gas group. Posterior capsular plaque (PCP) was seen in 41.67 % of silicone oil versus 7.32 % air/gas group; p < 0.005. Pupillary abnormalities were significantly more in oil (31.25 %) than in air/gas group (9.76 %); p = 0.014. Mean duration between vitrectomy and phacoemulsification in oil group versus air/gas group was 8.39 ± 4.7 months and 10.9 ± 5.22 months, respectively; p < 0.005. Mean postoperative logMAR visual acuity was better in air/gas (0.43 ± 0.25) than in oil (0.66 ± 0.29) group, p < 0.005. There was no significant difference in mean endothelial cell loss postoperatively in either groups (p = 0.25). Morphology of cataract differs in the two groups with PSC being more common in oil group. The mean time of cataract onset was significantly less in patients with oil group, and poor visual outcome in oil group may be attributable to the increased PCP noted.
