A Clinical Study in Transscleral Fixation of Foldable Intraocular Lenses

ABSTRACT

PURPOSE: To evaluate the results and complications of transscleral fixation of the foldable intraocular lens(IOL). METHODS: We performed a retrospective review of the medical records of 26 patients who had undergone transscleral fixation of acrylic three-piece foldable IOL from January 2002 to April 2004 in our hospital. There were 5 eyes with aphakia, 2 with idiopathic lens subluxation, 3 with trauma, 5 with dislocation or opacification of IOL, and 11 with complicated cataract surgery. RESULTS: The mean age of the patients was 70.6 years (range, 47~87 years). The range of preoperative best corrected visual acuity (BCVA) was from light perception to 0.6. The mean preoperative refraction and mean preoperative target refraction were 2.0 +/- 6.51D (-8.5~13D) and -0.45 +/- 0.70D (-3.75~0.39D), respectively, in spherical equivalent. The mean preoperative corneal astigmatism was -1.0 +/- 0.65D (-0.25~-2.5D). The postoperative BCVA ranged between 0.02 and 1.0, and the mean refractive error was -0.66 +/- 1.15D (-3.3~1.75D) at the last follow-up visit. The mean corneal astigmatism was -1.55D +/- 1.67 (-9~-0.25D) at the last follow-up visit (p=0.99, paired t-test). CONCLUSIONS: Transscleral fixation of the foldable IOL through small incision results in fewer complications, due to the large incision and the shorter time, and therefore, instantly improved visual acuity.
