Study provides new insights into cataracts

Researchers have taken a stage closer to comprehension how waterfalls structure by attaining a nearby up perspective of a protein that upholds the transparency of the lens in the human eye. 

Aquaporin zero (Aqp0) is a protein that structures water channels between eye cells called lens fibres, which are loaded with water and crystallin proteins. 

Specialists accept Aqp0 channels assume a significant part in controlling the volume of water in the lens fibres and looking after the transparency of the lens, with flaws in the gene that encodes the protein known to reason inherent and perhaps age-identified waterfalls.

 

Dr Houmam Araj, from the US National Institutes of Health's National Eye Institute, clarified: "Understanding the atomic portions of how water moves through the channel could prompt an improved comprehension of waterfall." 

The most recent study -which is distributed in the diary Nature Structural and Molecular Biology -empowered researchers to make computerised models of the Aqp0 protein interfacing with a divide protein called calmodulin, which controls the end of Aqp0 channels. 

Co-lead specialist Dr James Hall said that while waterfall surgery is adequate, the new discoveries "may be a stage to studying how to avert or delay waterfalls". 

Affordable And Safe Lasik Procedure

Devi Eye Hospital is happy to announce various latest technologies by using the most advanced laser machines to get rid of glasses permanently.

What is Lasik?

Lasik stands for “LASER-IN-SITU Keratomileusis” where in a Microkeratome or the laser beam (Intralase) creates a hinged corneal flap and laser beams then gently reshape the corneal bed and the flap is put back in position, which is a absolutely painless procedure.

Lasik is an out patient laser surgical procedure used to correct myopia (near sight), Hyperopia (far sight) and Astigmatism.

Why should you consider Lasik?

For many years the only way people could correct their vision was to wear spectacles. Over the last forty years, contact lenses have become increasingly popular as their design and availability has improved. Lasik has rapidly gained acceptance as a realistic alternative and enabled millions world wide to enjoy a new found freedom living lives without the inconvenience of glasses or contact lenses.

What are the types of lasik procedure?

a)    Zyoptix lasik procedure:-zyoptix technology will measure and correct irregularities in the optical system of the eye. Zyoptix is much more advanced and sophisticated from the regular lasik procedure.

In the worlds largest study evaluation of patient data comparing zyoptix treatment with standard lasik, zyoptix patients had significantly better vision than patients who underwent standard lasik.

b)    The Intralase method:- “the blade free lasik experience”. The intralase method is a 100% blade free approach to creating your corneal flap, the then flap of the tissue that the doctor folds back in order to perform your lasik procedure. Traditionally doctor’s have used an instrument called a microkeratome for the creation of corneal flaps. The microkeratome is a hand-held blade that moves across the eye, cutting the corneal flap as it goes,

The Intralase method, by contrast enables your doctor to create your corneal flap without a blade ever touching your eye.

The Intralase flap creation process takes almost 15 to 30 seconds. When lasik is complete, a flap created using the Intralase method is uniquely able to “LOCK” back into place. Your eye begins to rapidly heal. The intralase method also delivers outstanding visual results, patients report better quality of vision overall, particularly in terms of their ability to see well in low light, such as at dusk or at night.

Who are the patients not fit for lasik procedure?

·        Patients with very thin corneas

·        High refractive errors. (more than -14.0 D sphere

·        Unstable refraction.

·        Patients with ocular problems like Keretoconus (thin & irregular corneas), dry eye, past history of infections, etc.

·        Retina detachment & other hereditary retinal problems.

Is there any proven record?

The integrated approach that Zyoptix 100 brings to LASIK has helped eye surgeons achieve a much higher standard of visual accuracy, precision and safety in LASIK treatments. Many leading eye centres in the world adopt Zyoptix integrated system. In just over two years, over 100,000 LASIK procedures have been performed with Zyoptix.

What is the age limit?

Any person above the age of 18 years is a good candidate for lasik surgery. The glass / contact lens power should have been stable for the last 12 months.

 How long will the procedure take?

The procedure itself takes only a few minutes. You may have to spend a total of 2-3 hours in the hospital.

When can I get back to work?

You should be able to get back to work in 3-4 days. Both the eyes can be done on the same day.

Is it necessary to undergo repeat procedure?

In the rare event of an under correction or regression you may have to undergo a repeat procedure, at no extra cost. This depends on your corneal thickness and other factors which your surgeon decides.

Will the procedure hurt?

The lasik procedure itself is completely painless i.e. no injections. It is done using eye drops only. After the procedure you may have a mild discomfort in the form of a foreign body and watering sensation for a few hours.

What are the risks?

The chances of having vision reducing complications are less than 1%. There have been no reported cases of blindness from lasik so far. Some people may experience fluctuation in vision, glare and haloes at night which usually reduces with time. Patient over the age of 40 will require reading glasses. There are some rare complication (0.5%) like corneal ectasia, flap problem etc. “over I million lasik procedures have been performed world over in the last 10 years.

What should I expect before during and after LASIK surgery?

BEFORE SURGERY:-once you have decided to go ahead with lasik surgery, you will require a baseline evaluation by your doctor to determine if you are a good candidate. You should not feel pressurized by your doctor, family friends or anyone else to make a decision about having surgery. You should undergo only if you are totally convinced.

If you are wearing contact lenses it is necessary to stop wearing them before your baseline evaluation and switch to wearing your glasses full time.

Lasik is not done during pregnancy and loctation; clarify all your doubts and anxieties with the doctor.

The day before surgery, you should stop using creams, lotions, make-up or perfumes.

Arrange to be driven back after surgery as driving is not possible immediately after surgery.
