Abstract Details


To evaluate the outcomes in contrast sensitivity of LASIK with an aspheric micro-monovision protocol in patients with presbyopia


Departamento de OftalmologĂ­a. Hospital Universitario Quiron Madrid. Universidad Europea de Madrid


A prospective, non compartive case series included 100 eyes from 50 patients with presbyopia who where treated with Presby-LASIK. The CRS-Master software was used to generate ablation profiles for the MEL 80 excimer laser (Carl Zeis Meditec). Patients were classified in three groups according to spherical equivalent refractio: Group I (hyperopia), group II (myopia < 3 D) and group 3 (> 3 D). The contrast sensitivity was measured monocularly by means of CSV-1000, VectorVision Inc, preoperatively and 6 months after the surgery. Spatial frequencies studied were 3,6,12 and 18 cycles per degree (cpd)


The total mean spatial frecuency values in three groups were preoperatively 4.67,4.88,4.81 and 5.19 at 3,6,12 and 18 cycles/degree. After 6 month follow-up the values were 4.91,4.88, 4.90 and 5.01 respectively.No statiscally significant differences were found except to 3 cycles/degree values (p =0.017). No significant difference was found in spatial frecuencies in groups I and II. A small increase occurred at 18 cpg (p=0.021) in group III


The aspheric micro-monovision protocol for treating ammetropic patients was a well-tolerated and there is a small increase in contrast sensitivity at 6-month at 18 cpg in moderate myopic patients
