Abstract

Purpose: : To evaluate the difference between preoperatively predicted refractive errors and postoperative actual refractive errors according to combined or sequential cataract surgery in vitrectomy with or without gas tamponade.

Methods: : Thirty five patients(35 eyes) received combined surgery during vitrectomy and twenty six patients(26 eyes) underwent cataract surgery 3 months or later after vitrectomy were assigned to Group 1 and Group 2, respectively. Two groups were compared the discrepancy between predicted and actual refractive errors (DPARE) according to the procedures of gas tamponade or not at least 2 month after cataract surgery. Eyes affecting postoperative refractions, such as corneal or retinal complication, were excluded.

Results: : DPARE in Group 1 and Group 2 was +0.41±1.23 D and +0.37±0.93 D, respectively and there was no statistically significant difference between two groups. In Group 1, DPARE was -0.35±0.59 D in 12 eyes with gas tamponade and +0.77±1.35 D in eyes without gas tamponade. There was a statistically significant difference (p=0.01) between both subgroups of Group 1. In Group 2, however, DPARE of patients with (9 eyes) or without gas tamponade (17 eyes) was +0.29±0.76 D , +0.58±0.91 D, respectively and there was no statistically significant difference between them . In comparing between subgroups with gas tamponade procedure in Group1 and Group 2, DPARE was -0.35±0.59 D and +0.29±0.76 D, respectively (p=0.04).

Conclusions: : This study shows that we should consider myopic shift in combined cataract and vitrectomy surgery with gas tamponade due to possible forward displacement of the intraocular lens.
