Cataract surgery and IOL implantation have the safest and highest success rates of any eye care-related procedures. As with any type of surgery, however, some level of risk remains. [7] Most complications of cataract surgery do not result in long-term visual impairment, but some severe complications can lead to irreversible blindness. [90]
The cataract is removed from the capsule and anterior chamber using hydroexpression [Note 3] viscoexpression, [Note 4] or more-direct mechanical methods. [4] [13] [14] The extraction of the cataract must be done with due care so as not to compromise the integrity of the tunnel; the endothelium and capsule are also vulnerable to injury.
Cataract surgery by phacoemulsification is frequently performed under surface anaesthesia. Facial nerve, which supplies the orbicularis oculi muscle, is blocked in addition for intraocular surgeries. Topical anaesthesia is known to cause endothelial and epithelial toxicity, allergy and surface keratopathy. [citation needed]
Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure.
"Couching for cataract"; Wellcome Collection illustration of Indian doctors performing the technique. Couching is the earliest documented form of cataract surgery. It involves dislodging the lens of the eye, thus removing the cloudiness caused by the cataract. Couching was a precursor to modern cataract surgery and pars plana vitrectomy.
Cataracts: An often age-related condition that leads to gradual vision loss secondary to clouding of the lens. Examination may reveal opacification of the lens and often an absent or blunted red reflex. Dilated fundus exam allows for examination of more peripheral cataracts, as well as evaluating candidacy for cataract surgery. [9] [12]
