Abstract Details

Purpose:

To compare visual outcome and graft survival in eyes that had undergone simultaneous cataract extraction and penetrating keratoplasty (PKP), comparing to those have done cataract extraction after having PKP done before.

Setting:

Tanta University Ophthalmic Hospital, Egypt.

Methods:

Interventional case series. Triple procedure (PKP & open sky ECCE & IOL implantation) was performed in seventy three eyes of 73 patients, while phacoemulsification was performed in seventy eyes of 70 patients with previous keratoplasty with clear graft who developed significant cataract in the follow up period, were included in this study.

Results:

The mean age of the first group was 61.4±14.2 years. Mean follow-up period was 61.4±37.2 months over which mean BSCVA was significantly improved from 1.10 ± 0.38 to 0.48 ± 0.44 LogMAR (P<0.001). Mean postoperative spherical equivalent refractive error was -3. 25 ± 4.22 D. At final follow-up, 90% of the corneal grafts remained clear. In the second group, the phacoemulsification was done after PKP by mean period of 9 ± 1.8 months. The mean age was 41.4±14.2. Mean follow-up period was 36.4 ± 7.2 months over which mean BSCVA was significantly improved from 0.90 ± 0.38 to 0.58 ± 0.24 LogMAR (P<0.001). Mean postoperative spherical equivalent refractive error was -1. 25 ± 3.22 D. At final follow-up, all corneal grafts remained clear.

Conclusions:

Graft survival was not affected by cataract extraction. Visual outcome was better, more acceptable residual refractive error, without refractive surprises were obtained in separate sessions than simultaneous technique. This may be attributed to better graft stability, and accurate IOL calculation, and better control of astigmatism. FINANCIAL INTEREST: NONE
