One of the challenging situations for a cataract surgeon is phacoemulsification in the shallow anterior chamber like cases of phacomorphic glaucoma. Some of the main concerns of operating in a narrow space include endothelial decompensation, descemet's detachment, and posterior capsular rents. High vitreous pressure predisposes to posterior capsular rents owing to a reduced concavity of the posterior capsule and increasing the proximity of phaco-tip to the posterior capsule. We describe a technique of limited vitrectomy in such cases. A small gauge 23-G/25-G trocar cannula is passed transconjunctivally, and the liquefied vitreous is allowed to egress. Vitrectomy is done extraocularly till the vitreous pressure lowers down. This technique helps to debulk the vitreous and decompress the globe in a controlled manner. The resultant posterior displacement of iris-lens diaphragm causes a deepening of the anterior chamber to facilitate phacoemulsification.
