title: Final surgical results with a suction trephine.
abstract: The suction trephine was studied in 31 aphakic and pseudophakic penetrating keratoplasty patients (31 eyes). The postoperative corneal astigmatism averaged 3.9 +/- 2.8 diopters overall. The 15 pseudophakic cases in nonscarred corneas showed a marked reduction in postoperative corneal astigmatism (3.59 diopters) when compared to previous reports. Our results have encouraged us to continue use of the suction trephine in all aphakic or combined keratoplasty procedures.
