Nanophthalmos refers to an eyeball of short axial length, usually less than 20 mm which leads to angle closure glaucoma due to relatively large lens. Intra-ocular lens extraction relieves the angle closure in nanophthalmos. Cataract surgery in a nanophthalmic eye is technically difficult with high risk of complications such as posterior capsular rupture, uveal effusion, choroidal haemorrhage, vitreous haemorrhage, malignant glaucoma, retinal detachment and aqueous misdirection. Various options are explained in the literature to perform cataract surgery in nanophthalmos, like extracapsular cataract extraction with or without sclerostomy; small-incision cataract extraction by phacoemulsification which not only helps maintain the anterior chamber during surgery but also reduces the incidence of complications due to less fluctuation of intraocular pressure (IOP) during the surgery. Cataract surgery deepens and widens the anterior chamber angle in nanophthalmic eyes and has beneficial effects on IOP in eyes with nanophthalmos but is associated with a high incidence of complications.
