In PRK, photorefractive keratectomy, surgery, the use of laser is done to correct moderate degree of astigmatism, nearsightedness and farsightedness. Like Lasik surgery, here also the laser is used to reshape the cornea. But the difference is that in this surgery the laser is used on the surface of the cornea, not under the flab of cornea. This surgery can also be done with the computer image of the cornea.

The lasek surgery has some resemblance with Laser Eye Surgery in Delhi   the PRK surgery. In this surgery, an epithellai cells are treated with alcohol to loosen them before creating flab. The laser is used to reshape the cornea. The flab is then replaced and covered with soft contact lens for healing.

The RLE, refractive lens exchange, surgery is like the surgery done to remove cataracts. In this surgery a small incision is made at the edge of the cornea. Then natural lens of the eye is removed and a silicon or plastic lens is put in its place. This surgery is done to correct the extreme cases of farsightedness or nearsightedness. For curing astigmatism issue, the Lasik procedure can be combined with this surgery. Often the people with dry eyes, thin cornea or any minor issue related to cornea are given RLE surgery.

EPILASIK is used to separate Eye Treatment Delhi India a thin cell layer from cornea to reshape the internal cornea with laser. The thin cell layer can be replaced or left according to the procedure of the surgery selected. Laser treated area is the covered with soft contact lens for healing.  The success rate of all these surgeries is more than 98 %. Person can take these surgeries as outpatient and don’t need hospitalization.  The patients have shown improvemts in vision after few days of treatment.  In rare cases, the issues of overcorrection or under correction, infection may occur. Sometimes the desired results may not come from one surgery and another surgery is required, but again the cases of this nature are very rare. 

Types and features of contact lens

Contact lens can correct the nearsightedness, farsightedness and astigmatism. Contact lenses are normally used by the people, who do not want to wear glasses.   For some it is part of their style statement. Contact lens can also give better vision for sports.

Broadly, contact lens are divided on the bases of the material of which they are made .Soft lens are made from the gel like plastic contain water, called hydro gels.  These types of lens cover the entire cornea.  The silicon hydrogel are the advanced type of soft contact lens that gives more oxygen to the eyes than normal soft contact lens.

GP contact lenses are made from rigid water less plastic. They are also called oxygen permeable lens .These lenses are used for high astigmatism. They are smaller in diameter and have sharper vision than soft lens. Hard lens are made from also from rigid plastic knows as PAMMA. This type of lens does not transmit oxygen to the eye.   However, these lenses are not used these days as they have been replaced by GP contact lens. Hybrid contact lens have rigid optical center made of GP lens material, which is surrounded by soft material for comfort in wearing.

Laser Eye Surgery Procedures and its Effects

Laser is used to reshape the surface of the eye to improve or correct myopia, hypermetropia and astigmatism. During the laser surgery, the computer controlled excimer laser is used to remove the microscopic amounts of tissues from the cornea of the eye. The aim of the laser treatment is to help a person to get to see clearly without the need for glasses or contact lens.

In use of lasers, some procedures are different from others. It is this difference which gives different name to laser surgeries. Actually, almost all surgeries involve use of laser for treatment. In a common procedure, a laser known as femtosecond laser is used to create a thin flab of cornea tissues, which is then lifted out of the way. The excimer laser is then used to reshape the underlying tissue. The flab is then replaced to cover the newly reshaped area. Even when a blade is used to create a flab of the cornea, the use of laser remains to reshape the cornea. In PPK surgery, thin layer of cornea is removed and then laser is used to reshape the underlying cornea.

Use of excimer laser is considered very cool since it does not burn any tissues but only vaporizes the small part of the cornea where it is projected. The diameter of the laser and number of pulses are carefully controlled by the computer so that the cornea surface can be reshaped. The procedures are performed after giving anesthesia eye drops and duration of the treatment is only 5 to 10 minutes for one eye. The time taken by laser to reshape the cornea surface is generally less than a minute.

Generally the surgeries Laser Eye Surgery in Delhi involving the use of laser are considered for those who do not want to use either contact lens or glasses. The other reason could be that they are doing kind of work, where use of glasses or contact lens is prohibited.  The use of laser surgery eliminates the need for wearing and maintaining contact lens. Any person wearing glasses or contact lens can have the laser treatment surgery, but there are some issues that need to be considered .A person who wants to have the laser surgery should be at least 20 years of age.

Halos or blurred vision may appear in some patients after treatment. If eyes become dry after surgery then lubricating drops are used. Some persons report extreme sensitivity to glare. Cases of infection are rare, but can occur. Regression, return of previous cases of vision problem, is the other rare side effect of the surgery.  

The Number of Eye Surgeries Performed With Laser

Eye laser treatment is a general name that is given to the number of surgeries that are performed on eye with laser. Lasik surgery, PRK, LASEK and EPI LASIK is some of the surgeries that are done with laser. The aim of all these surgeries is to correct the refractive errors.   The laser which is used in these surgeries is called ‘excimer ‘. The procedures of the laser surgery, the duration of the recovery time and use of some surgical instruments may differ from surgery to surgery.   All the surgeries are not suitable for all patients.  One particular surgery may be more effective to a patient than others. It is the doctor who is the best person to decide, which particular surgery can be performed on a patient.  The decision to select a particular surgery will depend on the best result, which can come from the surgery.

Lasik is the common eye surgery. In this surgery a flap is made in the cornea by laser or a blade. After reshaping the cornea flab is put back to the same place. The use of laser to create flab is considered more precise and accurate with fewer chances of complications. The cost of this surgery with laser may be more than the cost of surgery without laser use.

In Photorefractive Keratectomy, PPK, surgery, which is the other common surgery for eye treatment, flab is not created. It involves the removal of the portion of the surface of cornea .And then use of laser to reshape the cornea. This surgery is preferred by some patients simply because they do not want corneal flab. Some patients with thin corneas are considered best suited by PPK surgery than Lasik surgery. The recovery period is also longer in this surgery as compare to Lasik.

In lasek surgery Laser Eye Surgery in Delhi alcohol is applied to the corneal epithelium to loosen the outmost corneal cells. Then they are moved away for laser treatment.  There is no need to remove them for this surgery. After using laser to reshape the cornea, the sheet of epithelium cells is replaced and contact lens is put to let it heal.  This surgery is can be given to patients of thin cornea

In epi –Lasik surgery the flab is created but it is thinner and made of epithelial tissue.  After creating the flab, a surgeon, moves it aside for using laser to reshape the stroma. The movement of the flab is very small, just enough for the use of laser. The flab is then replaced and covered with contact lens bandages to heal.  Some doctors believe that this surgery is better option because the alcohol is not used and flab exists only in epithelium layer.

Major eye treatment centers in Delhi Eye Treatment Delhi India are equipped with all facilities for surgeries. However the consultation with the best eye surgeon should decide the course of treatment and use of particular surgery.

Lasik surgery procedure and its results

Lasik is surgery which is used to correct farsightedness, nearsightedness and astigmatism. In this surgery, a thin flap is created in the cornea by using blade or laser. The surgeon after folding the flap removes the corneal tissue by using an excimer laser. After removing the tissue, the flab is again put at the same place. In nearsighted the Lasik is done to flatten the cornea while in farsighted the cornea is made steeper. In astigmatism correction, the irregular cornea is given normal shape

Before the start of Lasik, the eye drops are used to prevent any issue during the surgery. Some medication is also given to help a patient to relax. When eyes are under the laser, eyes are kept open by an instrument called lid speculum. The surgeon then marks the cornea with an ink marker. A suction ring is kept at the front of the eye to avoid any loss of contact or eye movement that may affect the quality of the flab.

After creating the flab, the computer is used to adjust the excimer laser for particular prescription of the eye. Here the patient is asked to look at a light for a short time, while doctor watches the eye through a microscope as laser sends pulses of light into cornea. With the help of laser light the cornea is reshaped without much pain. Only some kind of little pressure is experienced in the eye .Lasik is performed on each eye separately.

Patient may feel some burning or itching sensation after the surgery. There may not be immediate clarity of vision, as some haziness and blur vision may continue for short time. But the vision will improve from next day. Normally LASIK Eye Surgery Delhi in all cases the improvement after Lasik is fast .However in rare cases, it may take some weeks to get the clear vision.
