Recovery of Visual Acuity After Epikeratophakia and Secondary Intraocular Lens Implantation for Aphakia

Abstract

Recovery of visual acuity was examined in a group of 40 cases reviewed retrospectively after secondary anterior chamber lens implantation and compared with that in 25 cases followed prospectively after epikeratophakia.At 6 months after surgery 68% of those who had received an intraocular lens and 64% of those who underwent epikeratophakia achieved 6/9 visual acuity or better with spectacle correction. However, whilst 95% of the secondary intraocular lens patients had attained 6/12 vision by this time only 72% of those in the epikeratophakia group had done so.Kaplan-Meier analysis showed that the intraocular lens group reached 6/12 vision much more quickly than the epikeratophakia group but this difference is much reduced by the time 6/9 vision is attained and is probably not important clinically.
