Types of Cataract Surgery . Cataract operation or surgery is the exclusion of the eye lens due to cataract. Cataract is an eye problem that involves the eye's crystalline lens. The eye develops a clouding that hinders the light from entering. During the operation, the crystalline lens that becomes cloudy is excluded and substituted by artificial lens.
The first successful cataract surgery was performed by Jacques Daviel in 1748. And the implantation of lens that is intraocular was introduced in 1940 by Harold Hidley. The ophthalmologist is the one who usually executes the surgery using a local anesthesia. The surgery is usually successful and others got with minor complications. And it is Charles Kelman who developed the phaoemulsification method..
The ophthalmologist usually performs different types of surgery, the phacoemulsification or phaco, the conventional ECCE or extracapsular cataract extraction and ICCE or Intracapsular cataract extraction. The intraocular lens is commonly place in these types of operation. During the phacoemulsification surgery, a lens that is foldable is usually used and the cut is usually small while in ECCE, lenses that are non-foldable are being used with large incision. Phacoemulsification is most common used type of surgery. An apparatus with an ultrasonic hand piece with a steel or titanium end tip is used in this method. The lens is emulsified during the surgery because of the vibration of the apparatus. Another instrument used in this process is the chopper or cracker. This is used to chop the core into tiny pieces. This makes the emulsification and the target of cortical substance easy to perform. In order to eject the remaining unimportant cortical material during the phacoemulsifiication, dual irrigation-aspiration (A-I) probe or bimanual I-A system is used. ECCE is used for clients with very tough cataract. It is made in the sclera or cornea of the eye and usually involves huge cut. ICCE is the most rarely used type of surgery because the complication is very high due to large cut used and the applied pressure on the vitreous body.
