Bimanual technique for placement of footplates of phakic intraocular lens in eyes with intraoperative miosis

Abstract

We describe and assess the efficiency of a novel technique of placing implantable collamer lens (ICL) footplates in the sulcus in poorly dilated pupils utilizing perioptic holes and two instruments simultaneously (Sinskey hook and ICL manipulator). Twelve eyes of 10 patients underwent ICL implantation through this technique. The technique employs a bimanual approach engaging perioptic holes in the eyes with intraoperative miosis. Perioptic holes were engaged with a Sinskey hook and pulled slightly back, while the footplates were tucked under the iris by using an ICL manipulator. All patients had uneventful surgery. At 1 week follow-up, uncorrected distance visual acuity (UCDVA) was −0.01 ± 0.04 logMAR with a mean vault of 606.17 ± 108.33 microns. No complications were noted. However, too small a pupil is a limiting factor; this technique can be of use in up to mid-dilated pupils. Bimanual placement of haptics of ICL may represent a safe and effective technique in insufficient mydriasis or intraoperative pupillary miosis.
