Abstract

PURPOSE: To evaluate the surgical result and complications of scleral fixation of foldable intraocular lenses.
METHODS
We reviewed the medical records of 17 patients who had undergone scleral fixation of acrylic three-piece foldable intraocular lens.
RESULTS
Uncorrected visual acuity were improved in all eyes with time. Postoperative best corrected visual acuity were better than preoperative best corrected visual acuity in 14 eyes from 1.18+/-0.84 to 0.26 +/-0.25 in logMAR visual acuity. Estimated refractive error were 0.01+/-0.34 diopter in spherical equivalent preoperatively and .0.59+/-1.00 diopter postoperatively (p=0.02, paired t-test). The corneal astigmatic changes (dK) of mild against-the-rule astigmatism decreased as time passed. There was no intraoperative bleeding. There were postoperative complications such as increased intraocular pressure in 2 eyes, corneal epithelial defect in 1 eye.
CONCLUSIONS
In cases of scleral fixation, by using acrylic foldable intraocular lens through small incision, we were able to reduce corneal astigmatism and complications due to large incision and therefore, improve visual acuity instantly.
