To evaluate long term safety, central vaulting and rate of complication in patients after ICL implantation.
This consecutive case series included 85 eyes with moderate to high myopia after ICL (model V4) implantation. Patients were examined preoperatively, at 1 week, 1 month, 3 months, 6 months, and yearly thereafter.We evaluated subjective refraction (spherical equivalent - SA), uncorrected visual acuity, best corrected visual acuity (BCVA), near visual acuity, intraocular pressure (IOP), central vaulting (measured with a Jaeger II device and the VISANTE OCT), variation in endothelial cell density and adverse events. Main autcome measure were central vaulting, BCVA, and rate of complication.
Mean follow-up was 74.1 ± 23.1 months (26 to 124 months). preoperative SA was -16.31 ± 5.43 dpt (range -7.75 to -31.75 dpt), mean preoperative BCVA was 0.52 ± 0.24. The SA was reduced postoperatively (1 month) to -0.97 ± 1.95 dpt, BCVA increased to 0.71 ± 0.93. The SA remained stable throughout the study period. Mean endothelial cell density showed an early reduction after implantation followed by a continuous slow decline. Central vaulting decreased from 456 ± 215 µm after one week to 187 ± 172 µm after ten years. Patientes with higher lens rises had lower central vaulting. ICL removal due to secundary cataract development was performed in 16.2% of the cases after ten years.
