Purpose : To compare results of hybrid hydrophilic acrylic PIOL & Collamer based PIOL as a safe & effective strategy for management of myopia.
Methods : 59 & 33 consecutive myopic eyes of patients aged 18-42 years underwent hybrid hydrophilic acrylic based PIOL (Implantable Phakic Contact Lens; IPCL @ Care Group) & Collamer based PIOL (Implantable Collamer Lens; ICL @ STAAR Surgicals) implantation respectively at a tertiary level teaching hospital in India. Primary outcome was improvement in uncorrected distance visual acuity (UCVA) & lens vault at 6 months. Vault >250µ was good & <250µ was low. Secondary outcome were complications.
Results : Preoperatively, spherical equivalent was -2.5 to -25.5 D in 2 comparable groups. UCVA improved equally in both groups (Improvement in ICL–82%,IPCL-81%,P value=1). Average lens vault was 615 µ (IPCL) & 629 µ (ICL), with almost all >250 µ at 6 months. 1 eye had small vault of 87 µ (IPCL) at 1 month, which was exchanged with a larger one. At 6 months, 2 eyes had low vault (IPCL-173, ICL-188) . 2 eyes of 1 patient had raised intra-ocular pressure (steroid responder), which was managed medically. 2 eyes had minimal cataractous changes (IPCL) & were observed.
Conclusion : Hybrid hydrophilic acrylic PIOL (IPCL) is as safe & effective option as Collamer based PIOL (ICL) for correction of myopia. The added advantage of low cost with IPCL make it a more affordable option than ICL.
