Abstract
Purpose: :
To evaluate long term safety, central vaulting and rate of complication in patients after ICL implantation.
Methods: :
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.
Results: :
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.
