Abstract Details

Purpose:

To evaluate an L-shaped pocket incision which is an asymmetric scleral tunnel incision with an L-shaped entrance for rigid IOL implantation and explantation

Setting:

Dr. G. Beiko Prof. Medical Corporation

Methods:

6mm PMMA IOL, acrylic and silicone foldable IOLs were removed through a 3×3mm L-shaped pocket incision (group 1, 15 eyes) and a 6 mm conventional linear incision (group 2, 15 eyes) before intrascleral fixation of IOLs. Uncorrected visual acuity, keratometry and corneal topography were examined before the operation and 7 days, 1 month, 2 months, 3 months after surgery. The preoperative and postoperative astigmatism were calculated by the vector analysis method and the surgically induced astigmatism (SIA) was compared between the groups

Results:

In all patients, explantation of the dislocated IOL was easy. The mean SIA values were 0.33±0.24D, 0.11±0.19D, 0.25±0.15D and 0.06±0.11D in group 1, and 1.15±0.73D, 0/97±0.63D, 0.98±0.52D and 1.02±0.59D in group 2 in 7 days, 1 month, 2 months, 3 months after surgery. SIA was statistically less in Group 1 than Group 2 (p<0.05). No intraoperative or postoperative complications occurred in any patients.

Conclusions:

An L-shaped pocket incision is useful for 6 mm PMMA IOLs, as well as other IOLs.
