Refractive Surgery

A refractive error is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity. It is the most common ailment affecting the human eye. Refractive errors include Myopia (Nearsightedness), Hypermetropia (Farsightedness), Astigmatism (Cylindrical errors) and Presbyopia. Refractive surgery is used to describe any of a variety of eye surgeries to correct refractive errors and thereby reduce or eliminate a person’s need for eyeglasses or contact lenses.

At Mahajan eye centre (MEC), we offer surgery for removal of spectacles by SMILE, LASIK Laser, ICL (Implantable Contact Lens) or RLE (Refractive Lens Exchange).


The most popular refractive surgery today is LASIK, a laser vision correction procedure that improves eyesight by reshaping the front surface of the eye with an excimer laser. “LASIK” is an acronym for “laser in situ keratomileusis,” which means, “to reshape the living cornea”.

We, at MEC, perform lasik on state-of-the-art high performance and versatile MEL 80 from world leader in opto-electronics, Zeiss. The machine is designed to make the correction of vision defects even safer, more patient-friendly and individual. All the parameters of this ultramodern work platform are oriented towards increasing efficiency, achieving optimum treatment results and the rapid recovery of vision. Key factors here are the very high ablation rate, the high-performance eyetracker system and individual treatment planning.


Zeiss MEL 80 Excimer Laser System

Range of power approved: Laser vision correction has been approved for myopia up to -12.00 D, hyperopia up to +6.00D and astigmatism upto 6.00 D depending upon corneal thickness and shape.

Age for Lasik: Patient should be greater than 18 years of age however a good candidate is one who has stable glasses and/or contact lens prescription. Most individuals by the age of 20-21 have reached a point at which their glasses prescription will remain relatively stable.

Pre-Lasik Workup: At MEC, we offer detailed pre-lasik workup with Corneal Topography (Atlas: Humphrey, USA), Corneal Pachymetry (thickness) (Sonomed, USA), Corneal Tomography (Pentacam: Oculus, Germany) and Retinal Periphery Examination with Indirect Ophthalmoscopy.

Procedure: Throughout the procedure the patient is awake and eye drops are the only anesthesia given (Topical) making the procedure essentially painless. Patient’s eyelids and lashes are cleansed for sterility and the lids are gently opened with an eye speculum. Patients keep on looking at a blinking red light that keeps eye properly positioned. During the flap creation phase one has a sensation of pressure and a grayness of vision. Then the laser is used and one will hear a rapid clicking sound. The flap is replaced and it takes about 1-2 minutes for it to stick down. The procedure takes about 5-10 minutes per eye. After the procedure, patients will be prescribed eye drops to help your eye heal. Also, vision may be a little blurry for a day or so. Most patients are able to return to work in 24 hours, and have continuing improvement in their vision over next 3-4 weeks.

Life of Laser Correction:The laser vision correction will generally last for the rest of your life. Current studies show that once the cornea has been modified by the current Excimer laser protocol such as LASIK, it tends to remain stable and stay modified permanently. There are rare cases of regression, which may be corrected with further surgery, but the vast majority of corrected eyes remain stable.

Implantable Contact Lens (ICL)/ Phakic IOLs

At MEC, we are proud to offer this state-of-the-art refractive error solution, especially useful for our patients who otherwise may not be fit for lasik surgery. This surgery corrects higher degree of refractive error. It involves intraocular augmentation of the natural lens with additional lens without removal of natural lens and does not need to removal like a normal contact lens (Phakic IOL).This procedure has many advantages including its correction of the widest range of refractive errors. At MEC, we prefer to chose or offer this procedure in case person is not fit for Lasik Laser Surgery

Refractive Lens Exchange (RLE)/ Clear Lens Extraction (CLE)

In this procedure we replace the natural clear lens with a suitable IOL, not unlike a cataract surgery. This procedure is used for high dioptric power where other refractive procedures may not be indicated due to any reason.
