Abstract Details

Purpose:

Evaluation of the visual and refractive results of additional correction using LASIK and PRK methods in patients with residual refractive error after previous cataract surgery.

Setting:

Eximer eye center (Moscow, St. Petersburg).

Methods:

The prospective open study included 57 patients (79 eyes) who previously underwent cataract phacoemulsification (n = 37) or refractive lensectomy (n = 42) with various IOL models implantation (2012-2017). The average age of patients was 50.8 ± 13.9 (19-79) years. Operations LASIK (91.1%) and PRK (8.9%) were carried out according to standard methods.The target refraction ranged from -0.25 to 0.25 D in most (97.5%) cases.The patients were divided into groups according to the type of residual refractive error (Group 1-myopia, group II - emmetropia and group III - hyperopia). The follow-up period ranged from 6 to 9 months.

Results:

In group II, Cyl was significantly higher compared with groups I and III. In group I, a significant (p<0.05) decrease in SE from -1.36±0.92 to -0.2±0.8 D was observed. In patients of group II, there was a slight increase in SE from 0±0.20 to 0.25±0.29 D (p<0.05). In group III, a significant  decrease was observed in SE from 1.27±0.69 to 0.43±0.49 D). In group II, the largest decrease in Cyl was observed from -1.6±1.0 to 0.03±1.1 D(p<0.01). In all groups, a statistically significant increase in UCFVA was observed.

Conclusions:

The high efficiency of the correction using the LASIK, PRK and femtoLASIK methods on pseudophakic eyes with the achievement of the target refraction in most of the studied cases was shown. This method can be used as an alternative to spectacle and contact correction.
