ABSTRACT
We evaluated visual acuity, refractive error, corneal astigmatism, and complications after transscleral fixation of posterior chamber lenses in 46 aphakic eyes of 45 patients from January 1992 to April 1999. According to the causes of aphakia, there were 20 eyes for senile cataract surgery, 15 eyes for traumatic cataract surgery, 11 eyes for retinal detachment surgery including lensectomy. We used PMMA lenses in 35 eyes but foldable lenses in the remaining eyes. Anterior vitrectomy was done in 14 eyes. In 8 eyes which had some capsular support, one haptic was inserted at ciliary sulcus and the other haptic was sutured. Postoperative uncorrected visual acuity(UCVA)and best-corrected visual acuity(BCVA)were best in senile cataract surgery group according to the causes of aphakia, better in PMMA lens group according to the lens type, and better in the combined anterior vitrectomy group. But, there was no significant difference in the proportion of the cases that BCVA after 1 month of operation was not less than preoperative BCVA, according to the causes of aphakia, lens types, or combined anterior vitrectomy. The postoperative refractive error showed mild myopic shift, and the corneal astigmatic change was within 1. 5 diopter and stable up to 2 month after operation and did not differ significantly according to lens types. The incidence of complications was not high. In conclusion, transscleral fixation of posterior chamber lens in aphakia is effective.
