Abstract Details


To evaluate the incidence of cataract after ICL phakic IOL (p-IOL) implantation with two different lens models, the V4b and V4c, in myopia and astigmatism.


Cornea & Refractive Service, Shroff Eye Centre, A-9 Kailash Colony, New Delhi - 110048, India.


1565 eyes of 791 patients underwent implantation of the STAAR ICL for myopia -5.25 to -21.25D (mean -12.62±1.36D) and astigmatism of 0.75 to 5.75 D (1.62±0.89D). 1163 eyes (74.3%) were implanted with the V4b pIOL and 402 eyes (25.7%) were implanted with the V4c pIOL. The mean patient age was 27.34±4.75 years (19 to 45 years). The mean follow up was 3.15±0.96 years in the V4b group, and 1.21±0.63 years in the V4c group. Primary outcome measures evaluated were uncorrected visual acuity (UCVA), vaulting of pIOL, residual cylinder, and complications.


9 eyes of 5 patients (0.57% of all eyes) developed cataract and required pIOL explantation and cataract surgery. The mean age of these patients was 39.23±6.98 years. 4 patients were between 40 and 45 years and one was younger than 30 years (p<.05). All explanted models were the V4b (p<.001). The mean spherical equivalent of these eyes was -18.0±3.67D (-13 to -22 D). 4 eyes had myopia >20D (p<.01). The mean time between pIOL implantation and cataract surgery was 1.3±2.6 years. The mean vault in the V4b group was 492±189 microns. The mean vault distance in the eyes that showed cataract (all V4b) was 115±101 microns. The mean vault in the V4c group was 586±161 microns.


The incidence of cataract formation following pIOL implantation was low. Eyes with phakic IOLs with a lower vault were prone to develop cataract. No eye with a V4c pIOL (Centreflow Lens) developed cataract due to increased aqueous humor perfusion. The rate of cataract formation was higher in older patients and higher refractive errors.
