First consult the eye specialist. Best thing is to go private channeling first. After that he will give a date for the hospital eye clinic.
Usually the doctor gives recommendation for the lens as well as the place to buy it. The lens comes with all other necessary accessories needed for the surgery.
Although the surgery is very small, it's really really important to keep the eye safe for like 3 months. The lens comes with an eye patch as well which the patient can use after the surgery
