Surgery is the only mean to treat cataract. The common symptoms of the cataract are:  cloudy vision, interference with daily activities like reading or watching TV, sensitive to light, especially to headlight, sunlight, halo or haze around lights. The increase in cataract condition can also decrease the ability to distinguish between colors. The double or multiple visions also starts in the initial stages of the cataract. This problem comes to an end with the growth of cataract. The patient suffering from cataract also may change frequently, the number of spectacles or eye glasses. Some persons with cataract also may get improved near vision with onset of cataract but this is temporarily and vision gets worse with growth in cataract.

Cataract surgery is done to remove the cloudy lens and put clear artificial lens in its place. The advanced cataract surgery is called phacoemulsification, or phaco. In this surgery, the cloudy lens is disintegrated into small pieces with the help of an ultrasonic probe. After gently washing out the debris, the new artificial lens is put in its place.  The incision of only 2.6millimeter is required in this surgery. This incision is self healing. The stitches are not required in this surgery.

Surgical Treatment

Surgical treatment depends on the health of the eye and assessment of the curvature of the cornea

The doctor may also dilate the eye to see the lens and back part of the eye .peripheral vision and eye pressure measurement is also done before the treatment begins .Surgery involves incision of 3mm at the edge of the cornea. After this, the lens is broken into small pieces and removed with the ultrasound process called phacoemulsification. Then a silicone or plastic lens is put in the place of old lens. This lens stays permanently and works normally focusing light on the retina. The wounds left after this type of surgery are so small that they do not require any suture to close them.

The cataract surgery is used for treatment of cataract by effectively removing the natural lens that has developed opacification. Cataract treatment is only done by removing the natural lens using different types of cataract surgery and replacing them with a clear plastic len which is known as intraocular lens. 

 For treatment of cataract and restoring normal vision, the use of Lasik laser is not beneficial and recommended by ophthalmologists. As if the ophthalmologists have effectively eliminated the glasses by using the Lasik laser, still the vision of the individuals would be blurry due to existence of cataract.
