ABSTRACT

PURPOSE:

To evaluate the effect of vitrectomy in IOL power calculation for cataract surgery in the eyes that previously performed vitrectomy.

METHODS:

This study comprised 41 eyes of 37consecutive patients who underwent cataract surgery after previous vitrectomy. IOL power calculation with the measurement of axial length and corneal power was conducted before vitrectomy and before cataract surgery. Target refractions at each surgery, assuming that the same power of IOL was implanted, were compared to actual manifest refraction after cataract surgery.

RESULTS:

There was no statistically significant change in both axial length and corneal power after vitrectomy (p>0.05). Before vitrectomy, target refraction was -0.22+/-0.61D compared to -0.37+/-0.52D before cataract surgery. The actual refraction after cataract surgery was -0.47+/-0.94D, and there were no significant differences among the three refractions (p>0.05).

CONCLUSIONS:

In the eyes that underwent vitrectomy, vitrectomy itself does not have an influence on calculating IOL power for cataract surgery.
