Abstract Details

Purpose:

To evaluate an L-shaped pocket incision which is an asymmetric scleral tunnel incision with an L-shaped entrance for dislocated IOL explantation.

Setting:

Department of Ophthalmology, Juntendo University Shizuoka Hospital, Shizuoka (Japan)

Methods:

Dislocated 6 mm PMMA IOL, acrylic and silicone foldable IOLs were removed through a 3 × 3 mm 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. According to the vector analysis, SIA was statistically less in Group 1 than Group 2 (p<0.05). At explantation of acrylic and silicone foldable IOLs, there is no need to cut the optics using any special instruments. It was not difficult to remove residual cortex, Soemmering’s rings, and the capsular tension ring. No intraoperative or postoperative complications occurred in any patients.

Conclusions:

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