Pupil size, axial length portend near vision outcome after monofocal IOL implantation

Small pupil size and short axial length were the only factors that helped predict good near vision outcomes after phacoemulsification and monofocal IOL implantation, according to a study.

The retrospective study included 84 eyes of 84 patients who underwent cataract surgery with monofocal IOL implantation. Mean patient age was 65.7 years. Mean postoperative follow-up was 2.38 months.

Postoperative near vision was considered good in 34 eyes and poor in 50 eyes. Mean near visual acuity was 0.38 in the good near vision group and 0.68 in the poor near vision group (P = .001).

Mean uncorrected distance visual acuity was 0.04 in the good near vision group and 0.07 in the poor near vision group. Mean best corrected distance visual acuity was 0.02 in the good near vision group and 0.03 in the poor near vision group. The between-group differences were statistically insignificant.

Mean pupil size was 3.24 mm in the good near vision group and 3.61 mm in the poor near vision group (P = .009). Mean axial length was 23.32 mm in the good near vision group and 24.01 mm in the poor near vision group (P = .013).

Associations between good near vision and pupil size smaller than 2.6 mm and axial length shorter than 23 mm were significant (P = .039 and P = .034, respectively), the authors said.
