- Abstract
- PURPOSE: To identify factors that influence near vision after monofocal intraocular lens (IOL) implantation for distance vision. METHODS: A retrospective review was conducted of patients who underwent cataract surgery with monofocal IOL implantation from October 2009 to April 2010 at Samsung Medical Center. Eyes were classified as having good (>= J4) or poor (< J4) near vision. Factors analyzed included age, sex, intraocular lens (IOL) movement, axial length, pupil size, degree and type of astigmatism, IOL type, total aberration, and higher-order aberrations. Binary logistic regression and odds ratios with 95% confidence intervals were determined. RESULTS: This retrospective study involved 84 eyes of 84 patients. Thirty-four eyes were classified as having good near vision and 50 eyes as having poor near vision. All groups had a postoperative uncorrected visual acuity greater than 0.2 logMAR (Snellen 20/32) and a refractive error within +/- 0.5 diopter of spherical equivalent. Pupil size and axial length were inversely associated with good near vision (P = .034 and .039, respectively). A pupil size smaller than 2.6 mm and an axial length less than 23.0 mm resulted in better near vision than larger measurements after monofocal IOL implantation for distant target. CONCLUSIONS: Among the factors analyzed, small pupil size and short axial length predicted good near vision after phacoemulsification and monofocal IOL implantation.
