Abstract
Purpose :
To analyze long term outcomes of aspheric micro-monovision LASIK for correction of presbyopia and myopia with or without astigmatism in Chinese population.
Methods :
Aspheric Prospective, non-comparative case series of 114 eyes of 57 patients with a mean age 44.9 ± 4.9 years (range: 38 to 62 years) treated bilaterally using an aspheric micro-monovision protocol. The target refraction was plano for the distance eye and between -0.75 and -2.25 diopters (D) for the near eye. Visual acuity, ocular aberrations, contrast sensitivity, corneal topography, amplitude of accommodation, binocular sensorial function, and satisfaction score questionnaires were evaluated at 3 years after surgery.
Results :
Three years after surgery, the mean spherical equivalent(SE)refraction in distance eye was -0.05 ± 0.23D, whereas the attempted and achieved SE in near eye were -1.31 ± 0.20 and -1.02 ± 0.31 D respectively. Ninety-five percent of eyes were within ±0.50 D of target correction of SE. Ninety-three percent of patients achieved simultaneously uncorrected distance visual acuity 0.0 logMAR (20/20) or better and uncorrected near visual acuity J2 (20/25) or better.Six percent of patients lost 2 Snellen lines of CDVA .The overall satisfaction score for surgery was 93±6. Secondary treatment was performed in 3 eyes (3% retreatment rate), and all secondary treatments were performed more than 1year after surgery.
Conclusions :
The aspheric micro-monovision protocol is an excellent option,well tolerated,stable and effective for treating myopic astigmatism and alleviating presbyopic symptoms simultaneously.
