How does the eye work?

The eye acts like a camera with two focusing components, the cornea and the natural crystalline lens. Clear image viewing is dependent on the light bending properties of these structures. The retina acts like the film of the camera, receiving the focused light rays.

When light is ideally focused, an eye may see 6/6 or 20/20. Conversely, when light rays are not optimally focused, images may appear blurry. This is called a "refractive error." The eye can have one or a combination of refractive errors, including myopia, hyperopia, presbyopia, and astigmatism.

Hyperopia (Farsightedness)

Farsighted individuals typically develop problems reading up close before the age of 40. The farsighted eye is usually slightly shorter than a normal eye and may have a flatter cornea. Thus, the light of distant objects focuses behind the retina unless the natural lens can compensate fully. Near objects require even greater focusing power to be seen clearly and therefore, blur more easily.

LASIK, Refractive Lens Exchange and Contact lenses are a few of the options available to correct farsightedness.

Presbyopia

Presbyopia is a condition that typically becomes noticeable for most people around age of 40-42. In children and young adults, the lens inside the eye can easily focus on distant and near objects. With age, the lens loses its ability to focus adequately.

Although presbyopia is not completely understood, it is thought that the lens and its supporting structures lose the ability to make the lens longer during close vision effort. To compensate, affected individuals usually find that holding reading material further away makes the image clearer. Ultimately, aids such as reading glasses are typically needed by the mid-forties.

Besides glasses, presbyopia can be dealt with in a number of ways. Options include: monovision and multifocal contact lenses, monovision laser vision correction, and new presbyopia correcting implant lenses.

Vision Correction Options

Today there are many options for vision correction ranging from eyeglasses and contact lenses to laser vision correction and lens implants. Dr. Jeevan Ladi at DLEI has been performing spectacle reduction surgery from 1991.
Vision Correction Options generally fall into four broad categories:

A fifth category that significantly contributes to eye health and improved vision is nutrition and vitamin supplements. This fifth category is a long term commitment and it is harder to measure its effectiveness on a specific vision problem. To determine the current state of your vision you need to visit your eye doctor for a Comprehensive Eye Exam. This will provide your physician with the information needed to recommend vision correction options.

Clear vision requires that light rays pass through the eye's cornea, pupil and lens, and focus directly on the retina. If the cornea's curvature is not perfect, light rays focus either in front of, or behind the retina, resulting in nearsighted, farsightedness or astigmatism.

Myopia or nearsightedness, Hyperopia or farsightedness, Astigmatism and Presbyopia or aging eye are collectively referred to as refractive errors, and the various surgical approaches for correcting these are collectively referred to as refractive surgery.

Lens Implants

Corrective artificial lens implants give people the option of living without glasses. This vision correction choice offers different options for the under 40 and the over 40 age groups.

Under 40 years of age

The Implantable Collamer Lens or ICL, sometimes called the Implantable Contact Lens, marketed by Staar Surgical in Monrovia, California, received U.S. Food and Drug Administration approval in late December 2005. More than 40,000 Visian ICL’s have already been implanted worldwide.

Over 40 years of age

The choice of lens implants for this age group is larger and more established, like Clear Lens Exchange (CLE) .

LASER VISION CORRECTION

Laser vision correction, often referred to as LASIK, is currently the number one elective procedure worldwide. LASIK (an acronym for the medical term, Laser Assisted In-Situ Keratomileusis), is an out-patient procedure that utilizes a cool ultraviolet light to precisely reshape the cornea to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Today, LASIK has surpassed other self-improvement procedures in popularity.

Since its introduction ten years ago, more than 10 million people worldwide have experienced this simple, quick laser procedure, with the numbers increasing each year. This procedure, which takes minutes to complete, has not only been shown to provide better than 6/6 vision in some cases, but also improve one’s physical image and self-esteem.

Nearsightedness, farsightedness and astigmatism are collectively referred to as refractive errors, and the various surgical approaches for correcting these are collectively referred to as refractive surgery.

Laser In-Situ Keratomileusis (LASIK) is a quick, painless procedure that treats virtually all levels of refractive errors. This procedure combines the precision of the excimer laser with the benefits of an instrument called an automated microkeratome by allowing the surgeon to treat the inside surface of the cornea. LASIK is performed by folding back a thin layer of the cornea without damaging the surface. The surgeon then uses the laser to reshape the cornea, improving the way light is focused on the retina. This results in clearer vision.

LASIK is a highly effective and time tested procedure performed to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. LASIK is performed as an outpatient procedure in the comfort and convenience of our clinic which has a separate LASIK theatre. Normally, the entire procedure lasts less than 20 minutes, with most patients experiencing an improvement in their vision immediately following the procedure. The LASIK procedure allows patients to enjoy a faster visual recovery than PRK and healing is quite rapid with little or no discomfort.

CUSTOMVUE LASIK
Advancing the Science of Custom Ablation

VISX STAR S4IR with "True" Wavefront Technology, Iris Registration and 3D Eye Tracking

The current generation of laser vision correction (LVC) is a lot more than simply customized wavefront ablation. The VISX Excimer Laser platform system includes multifactorial advances that create optimal outcomes for today's LVC patients. The CustomVue platform has at least six meaningful advances in addition to Wavefront customization that enhance clinical outcomes. These exciting advances include: the use of Fourier analysis; variable spot scanning; enlarged optical zone options; improved blend zones; iris registration; and pupil centroid shift compensation. Technology is advancing at an amazing and exciting rate. There has been much discussion in the field of Ophthalmology concerning the merits of wavefront customized LASIK versus wavefront optimized LASIK versus conventional LASIK. Yet these discussions are becoming outdated and irrelevant given the fact that only wavefront guided Custom treatment offers these other significant platform advances.

In short, the current generation of the VISX Star S4 IR Excimer Laser includes many more benefits than just the addition of a wavefront analyzer. These added elements allow our surgeons to give patients the best possible outcomes for laser vision correction today.

Wavefront technology was originally developed to help reduce distortions when viewing distant objects in space. Today, it is revolutionizing the refractive surgery industry.

Wavefront technology is incorporated into the Wavescan diagnostic system which allows our doctors to now identify, measure, and correct imperfections in a patient's eyes 25 times more precisely than with standard methods used for glasses and contact lenses.

Using Wavefront technology in conjunction with the Star S4 Laser, Doctor Dr Jeevan Ladi can take the digital information gathered by the Wavescan and develop an individualized treatment plan that can be transferred directly to the laser for a precise "High Definition" vision correction never before possible.

Because we value our commitment to our patients we utilize only state-of-the-art equipments based on its outstanding performance, quality, track record and safety features.

Our VISX Star S4IR laser with Wavefront Technology, Iris Registration and 3D eye tracking provides excellent predictability and has the most approvals by the FDA. This laser also has the widest treatment range. With the latest hardware and software upgrades, our laser features design improvements intended to shorten the treatment time and expand the lasers capabilities and accuracy.

To use the VISX STAR S4IR, the surgeon must become VISX certified which requires a thorough training process. More people in the United States (approximately 7 out of 10) have been treated with the "gold standard" VISX laser than all others put together. Our laser is the most trusted laser vision correction technology, chosen by more ophthalmologists in the U.S. A. and worldwide than all other lasers combined! Because the VISX Star S4IR is so successful it is the only laser we use.

The VISX Star Iris Registration System (IR) is the latest step in CustomVue technology pioneered by VISX. The idea is to insure the best alignment of the laser treatment pattern possible. The eye tends to rotate when a person changes from a seated to the lying position. This is often a fairly small amount of true rotation but is clinically significant when applying a laser vision correction application. In the past, registration marks would be applied to the eye by the surgeon before surgery and then compensated for under the laser manually. It was the surgeon's responsibility to adjust the patient's head position to compensate and correct for the ocular rotation. If this was not perfectly performed, it could result in misalignment of the laser treatment pattern. While the surgeon must always be prepared to make any necessary adjustments, the IR system aids the surgeon in this task by a computerized matching technique.

Rotation can occur when the patient changes from the seated to the lying position. This can result in misalignment of the laser treatment pattern.

How Does Iris Registration Work?

It starts at the examination, when an infrared image of the iris is obtained in the seated position and analyzed for the various characteristic features of the individuals' iris. At the time of the surgery, another infrared image is taken when the patient is lying down under the laser and these images are compared and superimposed. Any recognized rotation is then compensated for by the laser rotating the treatment plan using sophisticated software. This all occurs prior to initiation of the treatment pattern. The Iris Registration system recognizes and corrects any misalignment in the laser treatment pattern. The better the alignment of the laser treatment, the higher is the quality of the surgical result.

In addition to the rotational capabilities of the Visx IR system, the final benefit is achieved by precisely centering the laser application. This is referred to as "pupil centroid shift", which is a compensating technique unique to the Visx IR system. When the rotation alignment and pupil centroid shift systems are used, aberrations are reduced, and clinical studies have shown visual results are improved.

VISX Iris Registration (IR) System recognizes and corrects any misalignment in the laser treatment pattern.

If you are nearsighted, without your glasses or contact lenses, your world is most likely blurry and fuzzy. Laser vision correction (LVC) can help to make your world clear. At DLEI, we want to ensure you make an informed decision about your vision correction options.

Q. What is laser vision correction?
Ans. Laser vision correction is a simple procedure that uses the VISX Star laser to correct nearsightedness and astigmatism. During the treatment, the laser's cool beam of ultraviolet light removes a small amount of tissue, usually less than the thickness of a human hair. Short pulses of this cool beam laser light change the curvature of the cornea, allowing images to be more sharply focused on the retina. Just as glasses and contacts help you to see clearly, so does laser vision correction. But there are some guidelines: you must be at least 18 years of age, with healthy eyes and stable vision.

Q. Is laser vision correction safe?
Ans. Over 10 million LVC procedures have been performed worldwide in the past 10 years. Data obtained during exhaustive clinical trials shows that all patients experienced a significant improvement in uncorrected vision (vision without glasses or contact lenses) after laser vision correction.

Q. Why do people have LASIK surgery?
Ans. Research has shown that there are four main reasons that people choose to have LASIK. They are:·

Q. Do I need an examination first?
Ans. Prior to treatment, you will have a thorough eye examination, called a laser vision consultation, conducted at DLEI to determine whether your eyes are healthy and suitable for LVC. In addition, a detailed video and computer image is taken of your eye that will detail the curvature, shape, overall smoothness and regularity of the cornea.

Q. What can I expect on the day of LVC procedure?
Ans. Shortly after arrival at the surgery centre, anaesthetic drops will be placed in your eyes to numb them. In the laser room, you will be seated in a reclining chair, the surgeon will position your head under the laser. During the surgery, you will be asked to focus on a blinking red light while the laser removes microscopic amounts of tissue from the cornea. The laser will treat your eye for less than one minute and your total time in the laser area will be about 20 minutes. After your laser treatment is completed, drops will be placed on your eye for protection and comfort. While the actual procedure is painless due to the numbing eyedrops, you may experience some slight discomfort during the immediate postoperative period.

Q. How much time will I need to get LVC?
Ans. We recommend you plan to have laser vision correction when you can afford a few days to relax and enjoy the benefits of your new vision. A postoperative visit is required at 24 hours and your eyes may be light-sensitive for a short time. The healing of the eye occurs during this period so we recommend you take a day or two off from work and avoid any strenuous activity.

Q. What kind of vision can I expect with LVC?
Ans. This depends largely on the amount of correction required. Most people require a low to moderate degree of laser vision correction that should result in vision similar to that with glasses or contact lenses. Vision is usually blurry in the first day or two after the LVC procedure. It is expected that most patients should be able to legally drive without correction after about one week.

Q. Is laser vision correction affordable for me?
Ans. The affordability of LVC has never been greater. First, consider the cost of replacing your eyeglass frames and lenses or the repetitive costs of disposable contact lenses. With laser vision correction you can receive the greatest value: clear vision without glasses or contact lenses. Please call (Laser Vision Counsellor) for details 9922995549.

Q. What is Monovision?
Ans. Monovision is an attractive option for many patients over the age of 40. You can elect a non-surgical monovision or a surgical option. With non-surgical monovision you wear a contact lens in one eye for distant vision and the use of a near vision contact in the other eye. Usually your dominant eye is fit for distance. It takes some training to get used to the "monovision" technique, but most people can adjust well to it and eventually cease to notice that each eye is responsible for a different part of their vision. If you find that this technique works well for you, this can sometimes be simulated using LASIK surgery.

Q. How Much Does Corrective Eye Surgery Cost?
Ans. Corrective eye surgery has never been more affordable than it is today.
