To investigate complication rates and results of cataract surgery in a monocular patient compared to normal binocular cataract patients.

We retrospectively analyzed 84 eyes of 84 patients that had undergone phacoemulsification, intraocular lens implantation and were followed up for 6 months or more. The fellow eye condition was classified into two different groups: Group A (experimental group) and Group B (control group). The best corrected visual acuity (BCVA) before and after surgery, operation time, nucleus sclerosis, and complication rate between the two groups were compared.

Both groups showed a significant level of visual improvement after 6 months ( p < 0.01, 0.01). There was no significant difference in sex, age, preoperative lens opacity, pre- and postoperative visual acuity, spherical equivalent, astigmatism, and rate of complications (posterior capsule rupture [n = 1], uveitis [n = 1] vs. posterior capsule rupture [n = 3], intraocular lens capture [n = 1].

The present study showed no difference in surgical results between Groups A and B. The results demonstrated that cataract surgery in a monocular patient resulted in favorable visual improvement.
