Workup

Laboratory Studies

The usual preoperative workup as for cataract extraction is recommended.

Protocol varies from facility to facility and may include a chest x-ray, an ECG for patients older than 40 years, glucose and electrolyte studies, and a CBC count.

If patients are on blood thinners, prothrombin time (PT)/active partial thromboplastin time (PTT) or bleeding time may also be ordered.

Imaging Studies

A-scan biometry and IOL Master are recommended to determine the best power of IOL to be placed.

Using indirect ophthalmoscopy, a detailed examination of the peripheral retina must be undertaken, especially in patients with high myopia, to look for abnormalities (eg, lattice, holes, tears).
