Abstract

|
|
Purpose: To introduce a more efficient and time-saving scleral fixation technique for a posterior chamber foldable intraocular lens and to report the clinical results.
Methods: A foldable acrylic 3-Piece IOL was sutured to the sclera via a small corneal incision. The guiding hollow needle was not used, which differs from other ab externo techniques. Instead, the curved long needle was directly pulled out through the cornea. The scleral flap was not used to bury the scleral suture knot; Instead, the scleral suture knot was translocated at the temporal area.
Results: A total of 30 cases were studied retrospectively. The mean follow-up period was 2 years. The IOL was correctly positioned in all cases. There were no major complications, such as endophthalmitis or suture erosion through the conjunctiva.
Conclusions: Based on the authors’ experience, the modified ab externo and one-knot technique is a faster and easier technique than the conventional ab externo technique.
