Objective: To describe the outcomes of phacoemulsification with the implant of an acrylic intraocular lens (IOL) in cataracts of adult patients with and without uveitis Methods: Descriptive retrospective comparative study of 35 patients (45 eyes) with uveitis (group 1) and 38 (44 eyes) control patients (group 2), who were operated on by the same surgeon, and were homogeneous as regards sex, surgical technique, IOL (hydrophobic or hydrophilic) and follow-up. The pre-surgical characteristics of risk, the difficulties and intra-surgical and postsurgical complications, the date of posterior capsulotomy (PC) and the pre- and post-surgical visual acuity (VA), were analysed. Results: In both groups the coaxial phacoemulsification was used in 75% of the eyes, bimanual microincision cataract surgery (MICS) in 20% and micro-coaxial in the rest. The pre-surgical risk factors (P=.002, OR 6.83), the surgical difficulties and complications (P=.001, OR 7.54) and postsurgical complications (P=.069, OR 3.42) were more frequent in the uveitis group. In both 93% and 91% respectively of eyes improved 2 or more lines of VA. After an average follow-up of 4.9 years in both groups, 22.7% and 32% eyes (log-rank P=.357) needed PC. The hydrophilic IOLs needed PC earlier than the hydrophobic ones (log rank P=.001), neither the location nor the uveitis course influenced the PC rate. Conclusions: The consequences because of previous ocular inflammation make cataract surgery in uveitis more difficult, but with postsurgical complications, visual results and need of PC similar to our patients without inflammation.
