Purpose

To assess the influence of posterior staphyloma on the clinical outcomes in post corneal refractive surgery myopic eyes implanted with a trifocal intraocular lens (IOL).

Setting

Fernández-Vega Universitary Institute, Oviedo, Spain

Methods

We analyzed the visual and refractive outcomes of 106 eyes with a previous corneal refractive surgery for high myopia correction and who underwent cataract surgery with trifocal IOL implantation. Thirty-nine eyes were diagnosed with posterior staphyloma, and seventy as long eyes without posterior staphyloma. Corrected distance visual acuity (CDVA) before corneal refractive surgery and after trifocal IOL implantation was used to assess the safety of the surgery. Furthermore, the refractive outcomes were evaluated at six months of trifocal IOL implantation.

Results

After the surgery, the mean Snellen decimal CDVA ranged from 0.60 to 1.00 and 0.50 to 1.00 for the long eyes and staphyloma groups. In the long eyes group, 11.43% of the cases lost lines of CDVA after trifocal IOL implantation. In the staphyloma group, the percentage of eyes that lost lines of CDVA was 33.33%. The safety indexes were 1.08 and 1.03 for the long eyes and staphyloma groups. CDVA was 0.93 ± 0.09 and 0.75 ± 0.12 for the long eye and staphyloma groups. 97.14% and 83.33% of the eyes in the long eyes and staphyloma groups showed a postoperative spherical equivalent within ±1.00D. The percentage of eyes with spherical equivalent between -0.50D and +0.50D was 71.43% in the long eyes group and 44.44% in the staphyloma group.

Conclusions

The outcomes of the present study show that the presence of a posterior staphyloma significantly worse the expected visual and refractive outcomes in post-corneal refractive surgery myopic eyes.
