In their recent article in the ARCHIVES, Harbour et al1 state that for malignant glaucomas, lensectomy may be considered only for marked corneal edema, for dense cataract, or at times when the anterior chamber will not deepen during vitrectomy in phakic eyes.
However, in eyes with malignant glaucoma, it is difficult to remove the vitreous base completely during vitrectomy without performing lensectomy. In such cases, the risk of cataract is high, as instruments can easily touch the lens. This results in additional intervention for lens removal at a later date.
