Laser Refractive Surgery

Laser refractive surgery is a procedure that involves reshaping the surface of the cornea using a laser to change the focus of the eye. This is typically performed on patients wishing to reduce their need for spectacles and, in many instances, completely eradicating the need for spectacles.

The procedure is a safe and effective procedure. However, it does need to be practiced in a responsible fashion. Dr Singh is a partner at Hunter Laser Vision, but thus established a laser correction vision practice in the Hunter area, where state of the art equipment is used for treating patients.

The laser platform using the Schwind Amaris 750 and the IntraLase (60 kHz platform) is used to create the flaps during LASIK.

Broadly there are two ways of treating patients with laser. One is LASIK and the other is PRK or otherwise sometimes known as advanced surface laser ablation (ASLA).

1. LASIK stands for laser-assisted intracorneal keratomileusis. In this procedure, a flap is created in the cornea (that is using the IntraLase femtosecond laser) which is then lifted and the treatment performed with the excimer laser onto the corneal bed underneath the flap (using the Schwind Amaris 750S). The flap is then replaced and the eye drops are commenced on the day of surgery. Usually there is a marked improvement in vision on the first postoperative day. LASIK can be used to treat both shortsightedness and longsightedness. A consultation with Dr Singh will determine whether you are suitable for this procedure.

2. PRK stands for phototherapeutic keratectomy. It is also known as ASLA (advanced surface laser ablation). In this procedure, no corneal flap is lifted from the cornea. Instead, a brush or laser is used to remove the surface cells of the cornea. The treatment is then applied directly to the cornea. After this, a contact lens is placed over the eye as a bandage as without it this can be quite an uncomfortable procedure. While PRK has similar results to LASIK, it has a slightly slower visual recovery time. Typically, patients undergoing PRK will notice a stepwise improvement in vision from week to week and usually vision reaches its stable point at around week six. During the early stage of the procedure, patients can feel their vision is quite fuzzy, which is quite normal. Most patients, however, are quite functional during this period.

If you would like to discuss laser refractive surgery, please make an appointment to see Dr Singh who will discuss the options further with you.
