Modern extracapsular cataract extraction surgery involves removal of the lens fibres, which form the nucleus and cortex of the cataract, leaving the posterior epithelial capsule to hold the new artificial intraocular lens (IOL) and keep the vitreous humour away from the anterior chamber. Extracapsular techniques of cataract extraction surgery originally involved manual nuclear expression. Phacoemulsification is a mechanically assisted extracapsular technique of cataract extraction surgery.
Indications: The most common indication for cataract surgery via phacoemulsification with intraocular lens implantation is the patient's desire to improve vision. If a patient's best corrected visual acuity does not meet government agencies and industries minimum standards of visual function for tasks for driving, flying, or operating complex equipment, cataract surgery via phacoemulsification with…
