Wearing spectacles to improve vision for far and nearby things is not always comfortable for some people. Therefore, many modern techniques have come up to treat vision problems. Like all modern techniques, Lasik Surgery treat only the pupillary axis.
2.It consists of a special topolyzer that helps mark and remove corneal irregularities.
...
... 3.IT helps create an optically perfect smooth surface of the cornea, enhancing visual sharpness and quality.
4.This is much beyond power correction.
5.This also helps treat corneal curvature, which other surgical treatments can’t.
6.There are no side effects if preoperative evaluation is done well, and
7.The healing time is faster in Contoura than in LASIK surgery.
8.Compared to others, the Contoura vision has the advantage that the physician can adjust the Q value, which defines the shape of the cornea.
9.When pre and post-operative topographies of the cornea were checked after treatment from Contoura vision, the uniform ablation zone was formed, which was missing in refractive wave front-optimized treatment.
10.It comprises computerized eye movement tracking, which ensures that when the laser is used, it delivers pulses with more accuracy. This feature is absent in other corneal treatments such as SMILE.
11.The rate and time of recovery in Contoura are very fast, while SMILE treatment takes 7-10 days.
12.It helps treat astigmatism, while LASIK and SMILE do not help in treating astigmatism.
13.Eye treatment is also beneficial to those people who drive at night. This modern treatment can reduce vision problems in low light conditions.
14.The eye treatment is also beneficial to those people who drive at night. This modern treatment can reduce vision problems in low light conditions.

Lasik Laser

LASIK is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. LASIK stands for Laser-Assisted In-Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A mechanical microkeratome (a blade device) or a laser keratome (a laser device) is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middle section of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced. There are other techniques and many new terms related to LASIK that you may hear about.
Below is a video that summarizes some risks of LASIK surgery and other important information. The video includes images of common visual problems that a LASIK patient may see. Please be sure to visit the other sections of this web site to get more information.
The treatment is simple and takes only about 10 minutes to perform. The following steps ensure care & safety during the procedure:

1.Eyelids and lashes are cleaned
2.We instil Antibiotic anaesthetic drops in the eye.
3.The patient lies back comfortably on a reclining operating table.
4.A protective corneal flap is created and gently lifted, revealing the inner corneal tissue. Since the corneal flap preserves the surface layer (epithelium) of the cornea, discomfort following LASIK procedure is minimal.
5.The computer within the laser machine is loaded with all the information of the pre-procedure tests.
6.The system calculates the required corneal treatment and directs the laser. Computer controlled pulses of cool laser light are applied to the inner layers of cornea. As the laser pulses, it makes a ticking sound. The inner corneal layer is reshaped with the laser to mimic your contact lens or prescription glasses.
7.The surgeon gently places the flap back and aligns it to its original position.
8.The flap heals naturally and securely.
