Abstract

Posterior chamber intraocular lenses were implanted into 40 eyes with inadequate capsular or zonular support by securing both haptics of the lenses to the sclera at ciliary sulcus with 10-0 prolene sutures. Our follow-up of 36 eyes with scleral fixated posterior chamber intraocular lenses ranged from 2 months to 8 months(average 4.6 months). At the last follow-up visit. 31 eyes(86%) had a vision of 0.5 or better. Mean refractive error was -1.15 +/- 1.13D. which was -0.67 +/- 0.99D more myopic than predicted (p<0.05). Measurement of anterior chamber depth showed deeper than the control group of posterior chamber intraocular lenses without scleral fixation suture(4.18 +/- 0.42mm, 3.96 +/- 0.29mm, respectively), but which was not statistically significant(p>0.05). Additionally, the difference of postoperative axial length between two groups was not statistically significant(23.39 +/- 0.87mm, 23.42 +/- 0.75mm, respectively). In 4 eyes(ll %), minor intraoperative bleeding oceured but was absorbed spontaneously without any sequelae. One eye(3%) of minimal decentration of PCL, one eye(3%) of subluxation of PCL, and one eye(3%) of exposed scleral fixation suture were noted, but no serious postoperative complication, such as corneal edema, glaucoma, persistent uveitis, or retinal detachment was detected.
