Abstract Details

Purpose:

Comparative analysis of the effectiveness of LASIK and secondary IOLs implantation for the correction of refractive errors in pseudophakic eyes

Setting:

Excimer Eye Center, Moscow, Russia

Methods:

A prospective open-label study included 74 patients (98 eyes) who underwent phacoemulsification (n=53) or lensectomy (n=45) with implantation of various IOL models as the first stage. The criterion for the inclusion of patients in the study was the presence of refractive error after implantation of an intraocular lens for periods of 6 months or more, requiring additional surgical intervention. Men accounted for 52.7% (n=39), women - 47.3% (n=35). Average age was 51.7±11.2 years. Group I consisted of patients who underwent LASIK (n=72; 73.5%) ,group II -26 with implantation of an additional Rayner Sulcoflex IOL (n=19) and Add-on Torica-sPB A4FW (n=7).

Results:

In group I there were no changes in spherical equivalent. A statistically significant (p˂0.05) decrease in the cylindrical equivalent from -0.93±1.35 to -0.12±0.73 was noted. Significant (p˂0.05) increase in UCDVA was observed from 0.37±0.16 to 0.76±0.19, and BCDVA remained same. In group II significant (p˂0.05) increase in UCDVA was from 0.26±0.21 to 0.84±0.16. A decrease in SE from -0.07 ± 3.3 to 0.02 ± 0.48 and the cylindrical component of refraction from -1.17±2.4 to -0.55±0.91 (p˂0.05) were noted. Safety/efficiency index in group I/II were 1.03/0.92 and 1.06/0.99, respectively; p˂0.05).

Conclusions:

A comparative analysis confirmed the effectiveness of LASIK and implantation of secondary IOLs as effective methods for correcting refractive errors in pseudophakic eyes. All groups showed a significant increase in UDVA. LASIK performance is associated with a significant reduction in the cylindrical refractive component. Efficiency and safety indices were comparable in both groups. For the correction of residual high myopia and hyperopia, implantation of additional IOLs is recommended, and for the correction of low and moderate myopia, as well as low hyperopia - LASIK.The data obtained allow us to recommend the use of both methods of correction in clinical practice.
