Özet
Purpose: The aim of our study was to determine a reliable, effective and predictable protocol for suture cutting to manage corneal astigmatism after cataract surgery. Material and Method: Selective suture cutting (from one to five sutures) was performed in 40 eyes with high with-the-rule astigmatism (≥ 3 D) following cataract extraction. Corneal astigmatism and axis were measured by a keratometer before and 2, 15, 30, 60 min. and one week after suture cutting. Results: An average of 3.86 D astigmatic correction was achieved for each suture cutting after one week following the procedure. The axis of astigmatism was found to shift an average of 20.7 degrees in each suture cutting at the end of one week. Most part of astigmatic (83%) and axis changes (78%) occurred within the first 30 minutes after suture cutting, but the remaining changes developed within one week. Conclusion: If high astigmatism still persists after first suture cutting following cataract surgery, it is not necessary to wait for a long period for cutting the remaining sutures and it is possible to cut following sutures after 30 minutes at the same session.
