Glaucoma Surgery in Dehradun

2015-03-13T10:17:18+00:00

Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of aqueous.

A trabeculoplasty is a modification of the trabecular meshwork. Laser trabeculoplasty (LTP) is the application of a laser beam to burn areas of the trabecular meshwork, located near the base of the iris, to increase fluid outflow. LTP is used in the treatment of various open-angle glaucomas. The two types of laser trabeculoplasty are argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT). As its name suggests, argon laser trabeculoplasty uses an argon laser to create tiny burns on the trabecular meshwork. Selective laser trabeculoplasty is newer technology that uses a Nd:YAG laser to target specific cells within the trabecular meshwork and create less thermal damage than ALT. SLT shows promise as a long term treatment. In SLT a laser is used to selectively target the melanocytes in the trabecular meshwork. Though the mechanism by which SLT functions is not well understood, it has been shown in trials to be as effective as the older Argon Laser Trabeculoplasty. However, because SLT is performed using a much lower power laser, it does not appear to affect the structure of the trabecular meshwork (based on electron microscopy) to the same extent, so retreatment may be possible if the effects from the original treatment should begin wear off, although this has not been proven in clinical studies. ALT is repeatable to some extent with measurable results possible.

Cataract Surgery in Dehradun

2015-03-13T10:15:28+00:00

Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. Many patients' first symptoms are strong glare from lights and small light sources at night, along with reduced acuity at low light levels. During cataract surgery, a patient's cloudy natural lens is removed and replaced with a synthetic lens to restore the lens's transparency.

Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is "implanted"). Cataract surgery is generally performed by an ophthalmologist (eye surgeon) in an ambulatory (rather than inpatient) setting, in a surgical center or hospital, using local anesthesia (either topical, peribulbar, or retrobulbar), usually causing little or no discomfort to the patient. Well over 90% of operations are successful in restoring useful vision, with a low complication rate. Day care, high volume, minimally invasive, small incision phacoemulsification with quick post-op recovery has become the standard of care in cataract surgery all over the world.

Phacoemulsification Treatment in Dehradun

Phacoemulsification refers to modern cataract surgery in which the eye's internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution, thus maintaining the anterior chamber, as well as cooling the handpiece.

Phacoemulsification treatment of subjects with acute primary angle closure and chronic primary angle-closure glaucoma.Phacoemulsification cataract surgery is a procedure in which an ultrasonic device is used to break up and then remove a cloudy lens, or cataract, from the eye to improve vision. The insertion of an intraocular lens (IOL) usually immediately follows phacoemulsification.

Phacoemulsification, or phaco, as surgeons refer to it, is used to restore vision in patients whose vision has become cloudy from cataracts. In the first stages of a cataract, people may notice only a slight cloudiness as it affects only a small part of the lens, the part of the eye that focuses light on the retina. As the cataract grows, it blocks more light and vision becomes cloudier. As vision worsens, the surgeon will recommend cataract surgery, usually phaco, to restore clear vision. With advancements in cataract surgery such as the IOL patients can sometimes experience dramatic vision improvement.

Phacoemulsification is a variation of extracapsular cataract extraction , a procedure in which the lens and the front portion of the capsule are removed. Formerly the most popular cataract surgery, the older method of extracapsular extraction involves a longer incision, about 0.4 in (10 mm), or almost half of the eye. Recovery from the larger incision extracapsular extraction also requires almost a week-long hospital stay after surgery, and limited physical activity for weeks or even months.

If your eye glasses are scratched, there’s no need to discard them. There are many ways to remove scratches without causing further damage. Many of these methods require nothing more than materials found around the house.

Use a cotton or soft wool cloth with a little non-abrasive toothpaste to quickly buff away scratches on eye glasses. Rub the lens gently, moving the cloth in small circles. Continue this motion for around ten seconds. Rinse with cold water and wipe dry.

For a very stubborn scratch, you may have to repeat the process. Continue until the scratch is completely removed. If you have an anti-scratch coating on your eye glasses, you may have to rub this off completely first. This will not damage the lens but will make it more difficult to get to the scratch.

Baking soda may also be used in this way. Make a thick paste from baking soda and water. Then, apply the paste with a soft cotton or wool cloth and rub gently in a circular motion. Rinse and wipe the lens dry. Again, the process may have to be repeated for deep or stubborn scratches.

Scratches on plastic eye glasses can be remedied by using Armor Etch, a glass etching compound. The active ingredient, Hydrofluoric Acid, removes the outer coating on plastic lenses. It should never be used on glass as it can damage the lenses further. For plastic eye glasses, simply place a thick coating of the compound onto each side of the lens. Allow the glasses to sit for five minutes. Rinse and wipe dry. Do not rub the compound into the lenses. The Armor Etch will remove the outer coating and any scratches along with it.

Another commercial product that works well for removing scratches from eye glasses is vehicle cleaning wax. Although it’s often used to polish automobiles, it can also fill in and remove scratches on glass and plastic eye glasses. Apply with a soft clean cloth and gently buff until the scratches have been removed. You may need to use several cloths as the wax adheres easily to fabric.

Windshield water repellants can also be used to remove scratches on eye glasses. They have the added bonus of repelling dirt and moisture, and preventing the glasses from fogging up during temperature changes. Simply apply with a soft cloth and polish gently for a few seconds. This treatment is best for superficial blemishes and may not be effective for deep, penetrating scratches.

Brass polish will remove scratches from plastic lenses but should not be used on glass. Apply with a cotton cloth and buff for several minutes. Rinsing isn’t necessary. Simply use a clean cloth to remove any excess polish from the eye glasses. Silver polish may also be used in the same manner.

These methods will remove scratches on eye glasses but should be used with care. Make sure to wear gloves and read all manufacturer handling instructions before using any of these products. Never use any abrasive solution on glass, or you risk causing severe damage to the lenses.

Lasik Services in Dehradun

LASIK (Laser In Situ Keratomileusis) is a laser surgical procedure effective for correcting all ranges of nearsightedness, farsightedness and astigmatism, except extremely high degrees. LASIK combines corneal flap surgery with excimer laser reshaping for dramatic results and rapid visual recovery.

To perform LASIK, an eye surgeon at our Bergen County, New Jersey ophthalmology practice first anesthetizes the eye with eye drops. The LASIK surgeon then creates a flap of tissue on the surface of the eye using a precise cutting instrument, called a microkeratome or the Intralase laser. This clear, hinged flap is lifted up and folded open, to the side or the top of the eye, exposing the inner corneal tissue.

Our New Jersey LASIK surgeon then positions the patient's eye under the excimer laser which is computer programmed to remove microscopic layers of tissue from the internal part of the cornea under the flap. During LASIK surgery the cornea is reshaped to allow the light rays to focus more clearly on the retina. After the tissue has been removed, the surgeon places the flap back in its original position where it heals into place with no stitches. The edges of the flap heal over in 12 to 48 hours, with the entire flap gaining adhesive strength as it continues to heal in the following weeks and months. For each eye, the laser application time is usually less than one minute and the whole LASIK procedure is around 15 minutes.

It is important that LASIK surgery candidates maintain realistic expectations about the outcomes of the procedure. Not all patients will achieve 20/20 vision after the operation. As with any surgery, the success of the procedure directly correlates with the skill of the surgeon. Each talented LASIK surgeon at Westwood Ophthalmology in Bergen County, New Jersey performs hundreds of successful procedures annually. If you live in or near northern New Jersey, trust a LASIK surgeon at our vision correction center to give you the best vision possible.

If you believe you are an ideal LASIK candidate and live near the Pascack Valley region of northern New Jersey, contact a qualified LASIK surgeon at Westwood ophthalmology to find out if LASIK surgery is right for you.

A measure of the tendency of an eyeglass lens material to cause chromatic aberration, which is an optical distortion that causes colored halos or fringes around lights or blurred vision, especially when looking through the periphery of the lens. The lower the Abbe number, the more likely chromatic aberration will be noticeable.These are simple eye care definitions and general information for common eye-related terms that we often use in our office. Explanations are then expanded based on the individual circumstances for each patient.

The fluid layer on the eye that helps keep the eye moist and nourished and provides a smooth surface for clear vision. The tears have three main components: a mucin layer is directly on the eye and helps smoothly spread the main watery layer over the eye, and a very thin lipid/fatty molecule layer on top to help slow evaporation.
Nearly clear, lens-shaped tissue behind the iris and pupil that is able to change shape to allow focusing from distance to near. The lens grows like an onion, layer by layer, getting thicker over time. The lens becomes a cataract when it becomes more cloudy or develops opacities.

Infertility Treatment Services in Dehradun

Infertility is the inability of a person, animal or plant to reproduce by natural means. It is usually not the natural state of a healthy adult organism, except notably among certain eusocial species (mostly haplodiploid insects).

In humans, infertility may describe a woman who is unable to conceive as well as being unable to carry a pregnancy to full term. There are many biological and other causes of infertility, including some that medical intervention can treat.[1] Infertility rates have increased by 4% since the 1980s, mostly from problems with fecundity due to an increase in age.[2] About 40% of the issues involved with infertility are due to the man, another 40% due to the woman, and 20% result from complications with both partners.[3]

Women who are fertile experience a natural period of fertility before and during ovulation, and they are naturally infertile during the rest of the menstrual cycle. Fertility awareness methods are used to discern when these changes occur by tracking changes in cervical mucus or basal body temperature.
