Title

INTRAOCULAR LENS POWER CALCULATION AFTER CORNEAL REFRACTIVE SURGERY

Pages

  10-16

Abstract

 Purpose: To report refractive outcomes following PHACOEMULSIFICATION (PE) and posterior chamber intraocular lens (PCIOL) implantation in eyes with previous corneal REFRACTIVE SURGERY.Methods: In this retrospective comparative study, 18 consecutive eyes of 14 patients with previous keratoREFRACTIVE SURGERY for myopia including photorefractive keratectomy (PRK, 6 eyes; 33.3%) and laser in situ keratomileusis (LASIK, 12 eyes; 66.7%) underwent PE+PCIOL. Computerized corneal topography was employed to determine the flattest keratometric reading within the 3-mm central zone. This value was inserted into the Sanders-Retzlaff-Kraff/T (SRK/T) formula to calculate IOL power. IOL power selected for implantation was 1 D greater than the calculated value described above.Results: Mean age and follow-up period were 54.1±11.5 years and 29.9±26.3 months, respectively. Mean implanted lens power was 18.56±3.86 D which was not significantly different from mean back-calculated IOL power for target refraction (19.04±4.16 D) (P=0.28). There was no significant difference between mean target refraction (-0.94±0.52 D) and achieved postoperative spherical equivalent refractive error (-0.62±1.06) at final follow-up (P=0.28). The achieved spherical equivalent refractive error was within ±0.50 D of intended refraction in 8 (44.4%) eyes, within ±1.0 D in 11 (61.1%) eyes, and within ±2.0 D in 16 (88.9%) eyes. In a subgroup of patients (5 eyes) with complete pre-REFRACTIVE SURGERY data, the difference between post-REFRACTIVE SURGERY keratometry method and all other methods (P=0.02) and between the current method and the Feiz-Mannis method (P=0.01) was statistically significant.Conclusion: The method suggested herein is simple and independent of pre-REFRACTIVE SURGERY data with results comparable to other commonly used methods.
