Abstract Details
Purpose:
To study the outcomes of a new design of aspheric, hydrophobic, acrylic IOLs with 4 unique holes in the optic margin.
Setting:
Dr Om Parkash Eye Institute
Methods:
Phacoemulsification was performed and acrylic IOL with optic holes were implanted from June 2018 (ongoing study). Hundred acrylic IOLs were designed with 4 holes close to the optic edge placed equidistantly.Optic size was 6 mm in diameter & holes 500 microns in diameter each.Aim was to allow complete removal of the fluid/viscoelastic substance from behind the IOL.These IOLs were compared with other aspheric hydrophobic IOLs in regard to presence/absence of capsular bag distension,IOL stability,shift in effective lens position (ELP) & posterior capsule(PC) wrinkling or opacification (PCO).Evaluation was done using OPD III scan, IOL master 700 & slit lamp images.
Results:
Slit lamp images and IOL master 700 revealed no/ minimal fluid pocket between the IOL and the capsule in all the cases on day 1 postoperatively. Cases with minimal fluid showed complete adherence of IOL to the PC over 2 weeks. None of the cases had PC wrinkling. IOL stability was observed on OPD III scan imaging over 3 months. No IOL rotation from the axis of implantation was noticed. No change in ELP was noticed thus preventing any immediate postoperative refractive surprise. No patient complained of dysphotopsia at 6 months post operatively.
Conclusions:
Acrylic IOLs with holes is beneficial in preventing early & late capsular bag distension, myopic refractive shift due to change in ELP, IOL tilt & PC wrinkling.IOL becomes stable in the bag with immediate effect that can be crucial for toric IOL stability.Long term evaluation is needed to comment on proposed reduction in the chances of PCO.
