Abstract

Purpose: : To determine the appropriate correction of predicted intraocular lens (IOL) power for a simultaneous vitrectomy and cataract surgery with a sulcus fixation of IOL

Methods: : We compared the spread between predicted and actual refraction in 18 eyes after simultaneous vitrectomy and phacoemulsification with a sulcus fixation of IOL (group 1), 40 eyes after simultaneous vitrectomy and phacoemulsification with posterior chamber IOL implantation (group 2), and in 85 eyes after cataract only (group 3). Axial lengths of all eyes were between 22mm and 25mm.

Results: : The spread between predicted and actual refraction (actual - predicted) was -1.3±0.73 diopters (D) in group 1, -0.50±0.79 D in group 2 and 0.03±0.57 D in group 3 (statically significant, p = 0.00). The actual refractive errors in the two combined surgery groups were found to shift toward myopia when compared with group 3. Among the combined surgery groups, group 1 showed a more myopic shift from the predicted in-the-bag refraction.

Conclusions: : Significant postoperative refractive errors occurred in study subjects. For a sulcus fixation for a simultaneous vitrectomy and cataract surgery, the IOL power should be approximately 1.5 D to 2.0 D less than the power for the in-the-bag fixation.
