Purpose
This study aims to evaluate the clinical and visual outcomes of corneal inlay explantation and its impact on keratometry and corneal thickness.
Setting
Beyoglu Eye Training and Research Hospital
Methods
Patients who underwent corneal inlay (KAMRA, AcuFocus Inc., Irvine, CA, USA) explantation between May 2014 and December 2024 in a single-center tertiary referral hospital were retrospectively analyzed. Twenty three eyes of 23 patients were included in the study. Patient demographics, post-operative results and complications were collected. Pre-operative and post-operative corrected distance visual acuity (CDVA), manifest refraction and Scheimpflug corneal topography (Sirius, CSO, Florence, Italy) were analyzed to evaluate outcomes. CDVA were measured using Snellen Chart and converted to logMAR.
Results
The mean age was 69.55±4.78 years and the mean interval between implantation and explantation was 9.67±3.75 years.The mean follow-up was 24.07±7.14 months after the explantation.Significant differences were observed between preop and postop mean CDVA(0.39±0.20, 0.20±0.14 logMAR respectively;p<0.01).The mean flat(K1) and steep axis(K2) were 45.43±2.08, 46.24±2.09diopters(D) preoperatively and 44.68±2.10, 45.76±2.14D postoperatively (p=0.01).Although a slight hyperopic shift was observed after explantation, it wasn’t significant(-0.37±3.18D, 0.06±1.58 D respectively;p=0.37).22 patients(95.65%) had postoperative residual donut-shaped corneal haze.6 patients developed cataract and underwent phacoemulsification with intraocular lens implantation
Conclusions
Corneal inlay removal is a safe option for patients with visual complaints. However, patients should be informed about the potential risks of postoperative hyperopic shift and donut haze.
