Purpose: To examine the refractive prediction error in high myopic eyes after phacovitrectomy

Methods: This retrospective comparative case series included one hundred one eyes (21 high myopic eyes and 80 non-high myopic eyes) of 101 patients who underwent successful phacovitrectomy (phacoemulsification, intraocular lens implantation, and pars plana vitrectomy). The high myopic eyes were defined as the eye with more than 26.0 mm of axial length. The post-operative prediction error of mean error and mean absolute error were evaluated at 4 months post-operatively. Axial length and keratometry measurement were performed pre-operatively and 4 months post-operatively using the IOL Master.

Results: The refractive outcome after phacovitrectomy showed significantly greater myopic shift in the high myopic eyes than that in the non-high myopic eyes. Axial length and keratometric value in the high myopic eyes were significantly increased (P=0.043, 0.037 respectively), whereas those in the non-high myopic group were not significantly increased (P=0.135, 0.347 respectively). The change of the axial length in the myopic eye (0.36±0.28 mm) was greater than in the non-high myopic eye (0.11±0.34 mm; P<0.001).

Conclusions: High myopic eyes showed more myopic shift than non-high myopic eyes after phacovitrectomy. The cause of myopic shift in high myopic eyes seems to be attributed to actual elongation of the axial length due to the thinner sclera in high myopia.
