Myopia
What is ‘Myopia’ or ‘Short Sightedness’?
In myopic patients, rays of light are focused at a point in front of the retina instead of on the retina. Due to this defect, a person can see near objects clearly but distant vision is blurred.
Causes of myopia
- Axial myopia– In the great majority of cases, myopia is axial, that is, it is due to an increase in the antero-posterior diameter of the eye. It is more commonly called the elongated eye.
- Curvature myopia– This is myopia caused by refractive errors resulting from excessive corneal curvature.
- Index myopia– This is caused due to the change in the refractive index of one or more media of the eye.
Symptoms that indicate Myopia If you are suffering from
- Blurred distance vision
- Eye-strain and headache
- Watering of the eye
Chances are you are Myopic. How to treat Myopia?
- Concave Spectacle Lenses
- Contact lenses– Soft & Gas Permeable
- Laser surgery for myopia – Lasik & Custom LASIK
- Phakic Intra Ocular Lens – ICL & Phakic Intra Ocular lens
- Refractive Lensectomy
LASIK is a safe and permanent treatment for myopia that eliminates the dependence of myopic patients on spectacles or contact lenses.
In a myopic LASIK procedure
- The doctor first creates a thin protective flap of corneal tissue using an instrument called the Microkeratome or by a blade-free procedure (Intralase Femtosecond laser).
- He gently lifts this flap, thereby exposing the deeper corneal layers.
- He uses an Excimer laser to remove tissue from the central portion of the cornea.
- This flattens the central corneal curve, refocusing light back on to the retina.
- He gently replaces the protective flap, where it heals naturally and securely.
This procedure is quick, painless and in most cases you can return to your normal activities very quickly, usually within hours.
