Phakic IOL implantation versus clear lens extraction in highly myopic eyes.

摘要

We appreciate Arne's idea of comparing phakic intraocular lens (IOL) implantation and clear lens extraction (CLE) in highly myopic eyes. However, we would like to comment on a few aspects of the study. The results would have been more conclusive if theinclusion criteria had been the same in both groups. There are 2 separate groups in the study. The phakic IOL group had a mean age of 35.7 years (range 32 to 43 years), whereas the CLE group had a mean age of 44.6 years (range 36 to 49 years). Also, the mean preoperative spherical equivalent refractive error was - 13.6 +- 3.0 diopters (D) in the phakic IOL group and -16.7 + 3.8 D in the CLE group. We think these are distinct groups and cannot be compared with each other. We also think that all the patients should be unilaterally or bilaterally recruited to increase the strength of the study.
