ABSTRACT

Objective

This study aimed to share our clinical results in myopic patients who underwent refractive lens

extraction and posterior chamber intraocular lens implantation (RLE + PCIOL).

Material and Methods

The data of myopic patients who underwent RLE + PCIOL implantation in our clinic between January 2004 and December 2009 were reviewed retrospectively. Preoperative and postoperative best uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (CDVA), refractive status, axial length (AL), biometric measurement, deviation from target refraction, and complication data were analyzed. The Sanders-Retzlaff-Kraff (SRK) II formula was used for preoperative intraocular lens (IOL)

calculations. Measurements were repeated with Sanders-Retzlaff-Kraff-Theoretical (SRK-T) and Hoffer Q formulas using preoperative data, and the results were compared with SRK II.

Results

Ninety-eight eyes of 57 myopic patients were included. Mean age was 37.91 ± 11.68 (18-59) years, and mean follow-up period was 35.12 ± 21.34 (6-78) months. Their AL was higher than 26.0 mm and their spherical value (SV) was higher than -8.00 diopters (D). There was significant improvement in UDVA, CDVA, SV, and spherical equivalent data at postoperative one month compared to preoperatively (all p< 0.001). Deviation from the target refraction was within the range of ± 1.00 D in 70 eyes (73.6%). A positive orrelation was found between AL and deviation from target refraction (r= 0.359, p= 0.001). Within the formulas, deviation from the target refraction was lower with SRK II (r= -0.371, p< 0.001).

Conclusion

Despite the risks of serious complications RLE + PCIOL implantation is a rapid and effective method in the visual rehabilitation of degenerative myopia. Degenerative myopic patients, especially those who have cataractous changes in the clear lens, and who are presbiyopic or approaching the presbyopic age, are more suitable candidates.
