Abstract

Purpose : To compare changes in refraction following lens-sparing vitrectomy between patients with rhegmatogenous retinal detachment (RRD) and epi-retinal membrane (ERM) and to investigate factors associated with the change in refraction.

Methods : We reviewed medical records of 49 eyes of 49 patients with RRD (53.6 ± 7.8 years) and 24 eyes of 24 patients with ERM (50.9 ± 15.7 years) who underwent lens-sparing vitrectomy. Spherical equivalent refractive power was evaluated before and up to 18 months after surgery. The relationship between the change in refraction and several parameters was evaluated.

Results : A significant progressive myopic shift in refractive power was observed after vitrectomy in operated RRD and ERM eyes (P < 0.001, P = 0.016, respectively), with no significant difference in fellow eyes. The change in refraction between RRD and ERM patients was significant (P = 0.030). The multiple linear regression analysis shows only age was significantly correlated with the change in refraction in RRD (P = 0.018) and ERM (P < 0.001) patients. The change in refraction was significantly and positively correlated with age in RRD (r = −0.461, P = 0.001) and ERM (r = −0.687, P < 0.001) patients. A significant difference in the frequency of cataract surgery in both groups was observed (P = 0.022).

Conclusions : Following lens-sparing vitrectomy for RRD and ERM, a progressive myopic shift in refraction due to nuclear sclerosis was observed. Core vitrectomy itself would cause a myopic shift of refraction. The only risk factor associated with cataract progression following lens-sparing vitrectomy is age for both types of patients.
