Abstract Details

Purpose:

Report of the case implanting phakic intraocular lenses to patients who have shallower ACD than guideline.

Setting:

Worked with patients who have been implanted phakic intraocular lenses at Nunevit Eye Center located in Busan, Korea during period of March, 2014 to October, 2015.

Methods:

Evaluating post-op physical effect to endothelial cell counts measured with specular microscope(CSO) regarding lens location and critical distance after implanting small size Artisan lens (model 202, 5.0/7.5) to 9 patients (17 eyes) generally considered as impossible selections to implant phakic intraocular lenses due to shallow ACD, (Pre-op mean ACD was 2.72(min 2.45) by Casia OCT, Tomey, and 2.71(min 2.48) by Pentacam Scheimpflug camera, Oculus)

Results:

Every implanted patient has showed stable clearance with critical distance above 1.0 mm. Changes of cornea endothelial cell counts also have maintained as following. Decrease of ECD 0.01%, CV 0.53%, %H 0.8% at 1 Mo., decrease of ECD 3.46%, CV 10.12% and increase of %H 9.69% at 6 Mo., decrease of ECD 1.23%, %H 6.80% and increase of CV 6.06% at 12 Mo..

Conclusions:

The purpose of pre-op ACD measurement for phakic intraocular lense implantation is to prevent trauma such as angle closure and cornea endothelial loss. Shallow ACD is contraindication of ICL due to high chance of angle closure and Artiflex cause to probability of endothelial cell damage. If we use small size Artisan lens (model 202, 5.0/7.5) with precise analyzing of anterior chamber, however, it might be possible to widen the scope of surgery.
