Abstract Details

Purpose:

To expose a case of refraction error after cataract surgery in a patient with angle-closure glaucoma

Setting:

Consorci Sanitari de Terrassa. Terrassa, Barcelona. Spain

Methods:

A 70 y.o. female patient with angle closure glaucoma was seen in our hospital in order to perform peripheral iridotomies.  Anterior Segment OCT (AS-OCT) showed a narrow angle of approximate 10º. Iridotomies were not totally successful and cataract surgery was proposed and accepted. IOL power calculation was done with IOL Master 700 biometer and a third generation formulas (Hoffer Q and SRK/T) were used to predict IOL power given that Hoffer Q formula is better in short eyes. Cataract surgery was performed in both eyes in a week interval

Results:

After a week refractive outcome was surprising, the first eye had a refraction of 0, the second eye was -3 Dioptres. Calculations were repeated with the same result, however IOL change was proposed to the patient and she recused. AS-OCT was repeated and proved that the lens did not move backwards.

Conclusions:

After cataract surgery in eyes with angle closure glaucoma, we expect a declining in intraocular pressure therefore a shortening of axial length and a deepening of the anterior chamber. In this case ACD did not change after surgery leading to a myopic shift in refraction.
