There is no medicine to prevent or slow the progression of cataract.Timing of surgery depends on the visual needs of the patient. It no longer requires ripening of the lens.
Surgery is usually outpatient and is done under topical anaesthesia.
Phacoemulsification : The only effective treatment for cataract is surgery. Cataract surgery involves removing the clouded lens and replacing it with a clear artifical lens(IOL-intraocular lens). Surgery is usually outpatient and is done under topical anaesthesia. Phaco emulsification is the most widely used Cataract surgery is the developed world. It uses Ultrasonic energy to emulsily and remove the cataractous lens through a very small incision in the cornea. It is a stitchless surgery as the incision is very small and requires no suturing.
IOL ( Intraocular Lenses ),Multifocal/Trifocal IOL,s are implanted in the eye after the Cataractous Lens has been removed by Phacoemulsification.
Monofocal Lenses Correct the distance vision and patient has to use glasses for near work.
Multifocal and Trifocal Lenses provide the patient with multiple focused vision for far and reading distance.
