Scleral no-stitch L-incisions for the implantation of rigid IOL with large opticsR. Hennekes, A. Claeys
Purpose: To determine the clinical properties and feasibility of large scleral no-stitch L-incisions allowing for the implantation of rigid IOL with large optics.
Methods: More than 600 cataract operations were performed using a 2.5 mm wide and 5.5 mm long scleral L-incision with a slightly oblique limb. PMMA lenses with 6.5 mm and 7.0 mm optics were implanted.
At month 1, year 1 and 2 surgical induced astigmatism (vector analysis) was determined.
Results: There were no incision related complications and particularly no postoperative wound leackage. In less than 1% of the cases a suture was placed. Surgically induced astigmatism amounted to 1.02 ± 0.6 dptr. at month 1. It declined in the postoperative period (2 years) and began to become statistically significant after a 3 years interval.
Discussion: A large scleral no-stitch L-incision is of excellent mechanical stability and high clinical safetyness. Postoperative astigmatic shift can be neglected even on a long-term scale.
