To investigate the clinical results of 44 high myopic eyes with cataracts which had minus diopter IOLs (Intraocular lenses) implanted during cataract surgery.

A retrospective chart review was done on 44 eyes in 33 patients who had undergone cataract extraction and minus diopter posterior chamber lens implantation. The IOL power was calculated using the SRK-T formula, and ACR6D SE® (Corneal SA, France) IOL was implanted in all cases. We evaluated pre-operative target refraction, post-operative refraction at six months, pre-operative visual acuity with and without correction, and post-operative visual acuity with and without correction. The relationships between axial length and refractive error and between the diopter of IOLs and refractive error were analyzed.

The mean postoperative hyperopic refractive error compared to the preoperative target refraction was +1.04±1.05D, which was statistically significant ( p <0.01). The longer the axial length and the larger the minus diopter lens inserted, the larger the hyperopic error. However, there were no statistically significant differences between them.

Satisfactory results in visual acuity were obtained after cataract surgery in high myopic patients. However, when choosing the IOL power in high myopic patients, the possible development of postoperative hyperopic error should be considered.
