    These IOLS provide both distance and near focus at the same time.

  • Accommodative IOLS

    These lens moves or changes shape inside your eye, allowing focusing at different distances.

Micro Incision Cataract Surgery (MICS)

MICS is an approach to cataract surgery by making an incision less than 1.8 mm with the purpose of reducing surgical invasiveness and improving surgical outcomes at the same time. The main confirmed advantages of MICS are the control & avoidance of surgically induced corneal astigmatism and the decrease of post-op corneal aberrations.

Pre-operative assessment

Before surgery, the specialist will assess the patient’s eyes and general health. The eye will be measured so that the replacement artificial lens can be prepared. You may be prescribed eyedrop medicines to start before surgery. These help to prevent infection after surgery.

Day after surgery

  • You will have to use eye drops after surgery

  • Avoid getting soap or water directly in the eye

  • Do not rub or press on your eye
