What is it about?
This article reviews all research articles on biometric and keratometric changes after trabeculectomy which is the most common surgical procedure for management of glaucoma.

Why is it important?
The review shows that, trabeculectomy can cause changes in axial length, anterior chamber depth, crystalline lens thickness, choroidal thickness, and corneal power. These changes may affect IOL power calculation in cases who need cataract surgery concurrent or some times after trabeculectomy.
Perspectives
We concluded that, in the case of phacotrabeculectomy, the refractive outcome of IOL implantation may remain reasonably predictable because of the opposite direction of axial length and corneal power changes. Instead, in a situation of subsequent cataract surgery, the best refractive outcomes may be achieved with delaying cataract surgery until biometric changes stabilize at approximately 6 months postoperatively. In addition, it is preferable to measure biometric parameters using noncontact optical biometry instead of contact ultrasonic biometry for IOL power calculations in such cases, especially when cataract surgery is needed shortly after the trabeculectomy.
