LASIK

LASIK Laser Vision Correction Surgery at Premier Eye Care

LASIK is used to correct refractive errors; LASIK eye surgery is a treatment that reshapes the cornea in order to produce clear vision. The LASIK refractive eye surgery procedure can treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, and reduce patient's dependency on contact lenses and glasses. Refractive errors impede the focusing ability of the eye, patients who suffer from these conditions experience blurred vision. LASIK eye surgery provides these individuals with an effective treatment option, where a predetermined amount of corneal tissue is removed. This reshaping of the cornea improves the eye’s focusing power and enhances patients’ visual acuity.

What are the various tests done before Lasik/Customized Lasik?

• Spectacle power assessment
• Corneal topography using Orbscan to assess the corneal thickness & curvature
• Aberrometry using Zwave for customized Lasik
• Comprehensive assessment External and Peripheral retinal examination after dilating the pupillary aperture of the eye

The entire preoperative assessment process may take about 1 hour.

What is the surgical procedure for laser vision correction?

The surgical procedure is relatively simple and takes only about 10-15 minutes for both the eyes. The anesthetic drops are first instilled to cause numbing of the eye. This may give rise to a slight burning sensation as soon as the drops are instilled.
A speculum is placed to separate the eyelids and to prevent the patient from closing the eye during the procedure. The patient is asked to focus on a red light. An instrument known as the microkeratome is then used to raise a thin flap (120-140µ) of the cornea. The red light may transiently disappear during this process. Alternatively the latest technique for making the flap is using a femto second laser (INTRALASE) to make a highly precise and customized thin flap. The excimer laser then reshapes the cornea by removing a predetermined precise amount of tissue from the inner cornea. The flap is then repositioned back where it adheres immediately without the need for stitches or bandages.

Visual recovery is full in 24-48 hours.

Different kinds of Laser Vision Correction

The various kinds of laser used in the Laser Vision Correction are:

• INTRALASIK
• LASIK
• Zyoptic
• Plano Lasik
• Epi Lasik

ICL (Implantable Contact Lens)

ICL is a high-tech yet a simple way of correcting your refractive error. Don't be disappointed if your doctor has denied Lasik procedure for your eyes. The following information gives you reassurance that you can still enjoy life without the constraints and restrictions of spectacles or contact lenses. No more problems for playing, jogging or swimming!

Procedure of ICL

The patient willing to get the ICL procedure done must stop the contact lenses for a specified period of time as mentioned above. Following tests are conducted in the hospital:

• Spectacle power assessment
• Corneal topography using OrbscanIIz to assess the corneal curvature, corneal diameter and anterior chamber depth.
• Peripheral Retinal Examination
• After the measurements, one has to wait for a period of 7 - 10 days, as these lenses need to be imported from Switzerland. During this waiting period, one can use their contact lenses.
