Abstract Details

Purpose:

The aim of our study was to analyze the influence of different surgical approaches on postoperative astigmatism after penetrating keratoplasty.

Methods:

This retrospective study included 38 patients (one eye of each patient, 20 males and 18 females), for which was indicated penetrating keratoplasty. The average patients age was 52.6 ± 18.5 years. Astigmatism was studied after removal all sutures ( average 4.2 months after removal ). We analyzed whether there is different size of postoperative astigmatism using different ways of trephination (same trephine size for donor and host, or bigger for donor) and suturing techniques (single interrupted suture technique, single running suturing and double running suture technique).

Results:

Most common indications for keratoplasty were keratoconus (26.3%), pseudophakic bullous keratopathy (18.4%) and Fuchs' dystrophy (14.4%). Preoperative best corrected visual acuty (BCVA) was: <0.1 (18 patients), 0.1-0.3 (20 patients). Postoperative BCVA was: 0.1-0.3 (10 patients), 0.4-0.7 (19 patients), 0.8-1.0 (9 patients).Average astigmatism after suture removal were 4,97 Dcyl. There was no significant difference in the size of astigmatism in different trephination approaches, as well as different suturing techniques.

Conclusions:

Despite of using various techniques of suturing, differences in trephination of the cornea donor and host, high postoperative astigmatism remains a common complication of penetrating keratoplasty, which is often necessary to correct with contact lenses, some of the methods of refractive surgery or with toric intraocular lenses.
