ABSTRACT

Silicone oil injection at the end of vitrectomy is common. Cataracts are also common when silicone oil needs to be removed from the eye. The question arises; should we remove the silicone oil first and at least two months later perform cataract and intraocular lens (IOL) implantation surgery? Or do two operations at the same time? The aim of the present study was to compare these two methods. Patients who had previously undergone vitrectomy and silicone oil injection and needed cataract surgery and silicone oil drainage were divided into two groups. In the first group, pars plana silicone oil removal was done first and at least two months later, cataract+IOL surgery was performed. In the second group cataract + IOL surgery and pars plana silicone oil removal was donein one step. In all patients, lens power was determined by IOL Master Device. There was no significant difference between the two groups in terms of age (P = 0.36) and gender (P = 0.88). The refractive error in the first and second groups was -0.75± 0.66 and -1.00± 0.99 diopter respectively, but the difference was not statistically significant (P = 0.44). The mean of uncorrected visual acuity six months after one-step and two-steps surgery was 1.20± 0.08 and 1.13± 0.17 Log MAR respectively, but the difference was not statistically significant (P = 0.18). Also, best corrected visual acuity six months after one-step and two-steps surgery was 0.98± 0.26 and 0.91± 0.28 Log MAR, respectively, which was not statistically significant (P = 0.27). In respect to no statistically significant difference between two groups and lower risk of complications of the one-step approach, including complications of anesthesia, as well as lower cost and fewer visits, we recommend surgeries should be performed in one step.
