High Definition Lasik Eye Surgery

For patients with moderate to high myopia or thin corneas which cannot be treated with LASIK and PRK, the phakic intraocular lens is an alternative.

The procedure involves creating a thin flap on the eye, folding it to enable remodeling of the tissue beneath with a laser and repositioning the flap.

Preoperative procedures

Contact lenses

Patients wearing soft contact lenses are instructed to stop wearing them 5 to 21 days before surgery, patients wearing hard contact lenses may require a longer period

Pre-operative examination and education

In the USA, the FDA has approved LASIK for age 18 and over.

The eye prescription should be stable for at least one year prior to surgery.

HD Lasik is contraindicated if the topographer finds difficulties such as keratoconus

Postoperative care

Patients are usually given a course of antibiotic and anti-inflammatory eye drops. These are continued in the weeks following surgery. Patients are told to rest and are given dark eyeglasses to protect their eyes from bright lights and occasionally protective goggles to prevent rubbing of the eyes when asleep and to reduce dry eyes. They also are required to moisturize the eyes with preservative-free tears and follow directions for prescription drops. Occasionally after the procedure a bandage contact lens is placed to aid the healing, and typically removed after 3–4 days

Dry eyes

Some people experience dry eyes following surgery. Although it is usually temporary it can develop into dry eye syndrome.

Underlying conditions with dry eye such as Sjögren’s syndrome are considered contraindications to Lasik.

Infection – the incidence of infection responsive to treatment has been estimated at 0.4%.

A report shows the incidence of subconjunctival hemorrhage has been estimated at 10.5%.

Onset of presbyopia people over 45 may still need reading spectacles after Hd Lasik or the surgeon may correct on eye for distance and the other for reading (monovision)
