Abstract Details

Purpose:

To determine the postoperative refractive error in eyes with intraocular gas tamponade in combined phacovitrectomy using a Z-haptic IOL.

Setting:

University Hospital Hamburg-Eppendorf.

Methods:

This prospective non-randomized case-control study compared patients with combined phacovitrectomy with or without intraocular gas tamponade to cataract surgery-only. The main outcome measure was the IOL power prediction error. Secondary outcome measures were the spherical equivalent, anterior chamber depth and axial length.

Results:

Thirty-four patients with epiretinal membranes and 18 patients with cataract only were enrolled. There were no statistically significant (P>0.05) differences of IOL power prediction error. No statistically significant between-group differences between secondary outcome measures were obtained. Eyes after vitrectomy showed deeper anterior chamber depths.

Conclusions:

A myopic shift after phacovitrectomy is independent of use of intraocular gas tamponade and should be taken into account in calculating IOL power. When using a Z-haptic IOL we suggest aiming for slight residual hyperopia (+0.50 Diopter) in patients having phacovitrectomy.
