Eyesight is one of the most precious gifts that nature has given to mankind. It’s only because of the eyes; one can enjoy the beauty of this world. It’s impossible to imagine life without sight. Though a very small part of body, eye is one of the most complex human organs. It has various parts, all of which are responsible for normal vision. Smallest structural or functional alteration in the functioning of an eye can cause tremendous visual disturbances.

Refractive error or need of glasses is one of the most common eye problems. It can start at any age. This is due to alteration in length, shape & / or capacity of eyes. There are various types of refractive errors which can be checked by an expert eye specialist & accordingly glasses can be used to improve clarity of vision. Other option for glasses is Contact Lenses. Glasses can be removed completely by a LASER procedure called LASIK after the age of 18 years once the power of eye is stabilized. LASIK is a very safe procedure with high grade accuracy, least possible side effects & excellent results. As refractive error can arise at any age, one eye check up by an eye specialist is must for each & every child at the age of 5 years irrespective whether he is having eye problems or not.

Cataract is another most common eye problem which is nothing but clouding of natural human lens. It’s not a disease but normal aging process. Hence it’s seen in old age commonly though it can occur at any age because of various reasons & can be there by birth also. Cataract affects quality of vision to a great extent. The only treatment for this is surgery. Cataract can’t be cured by glasses or medicines. Due to advances in technology, the entire surgery can be done through a very small 2.8 mm incision & high quality artificial lens is implanted in the eye. Its day care procedure, no hospitalization is required & patient can go home immediately after surgery.

Cataract has to be removed by advanced cataract surgery (Phacoemulsification) & replaced by modern intra-ocular lens

Squint or crossed eye is again a very common eye problem. It also can occur at any age & can be treated by glasses, exercises or surgery. Any person or child with squint has to be examined by expert squint specialist as early as possible irrespective of the age of the affected because if not treated in time, it can have severe impact on vision of the affected. Children with squint need special attention by squint specialist.

Squint corrected by surgery

Glaucoma, which is also called as silent thief of eyesight, occurs due to damage of the Optic Nerve. Raised pressure inside the eye is one of the main risk factors for this. This is also seen in old age & if not diagnosed & treated in time can cause gradual & permanent loss of vision. Treatment modalities include eye drops, LASER & surgery.

Though very small part of human body, eye is very important & delicate organ. Most of the diseases affecting eyes can have impact on the vision & hence any symptom of eye problem should be taken seriously & immediately eye check up by an expert eye specialist should be done to avoid vision threatening problems in future.

3 D HEADACHES

It’s a headache? … While watching a 3D movie? … Rush for an eye check up!

The growing popularity of 3- D movies such as James Cameron’s “Avatar” has inspired many other films to follow suit. Even movies for children like “Shrek Forever After and Toy Story-3” are being made in 3-D. Not to forget the new 3D television sets introduced recently!

While new digital 3D technology has made the entire movie experience exciting, for some people with eye problems, a prolonged 3D session of focussing for 120 minutes or more on rich 3 D images may result in an aching head.

And, if it does, it could very well indicate an eye problem!

Why would a 3 D movie result in headaches?

For people with normal vision, this headache or disorientation after watching a 3 D film is usual because we have trained our eyes to see movies in 2 D. In 2 D films, we see images in one plane, so the focussing efforts of the eye are minimalistic. No strain, no headache!

However, 3 D images are stacked in front of or behind some other layer depending on what the filmmakers want you to see. Our eyes have a natural tendency to bring images which are closer or further away into focus. 3D camerawork frustrates this instinct. That translates into greater mental effort, making it easier to get a headache.

With 3D movies, people face an entirely new sensory experience.

To see the image in 3 D, you firstly need the image in each eye to be equally clear and then merge the slightly different images presented to each eye. Ultimately, it is what your brain is telling your eyes to do that gives you the headache by creating the extra workload. This is similar to doing long hours of work on the computer. Only, in the movies one cannot take a break, but the eyes and brain need to concentrate for longer. Under normal circumstances, this may not be an issue and may just be a temporary discomfort that one is able to overcome.

In the movie, you are meant to focus where James Cameron wants you to focus! That frame is ‘brought out, panned out or comes into focus’. So, if you start looking elsewhere, at a creature or an animal on the side, you cannot focus on it and this is what gives anyone a disoriented sometimes nauseous feeling. So, to avoid a headache you have to ‘go with the flow’.

Red Alert for Others

On the other hand, a long lasting headache, nausea, disorientation or complete inability to perceive 3 D images could well mean an eye problem, most being minor and treatable. People who do not have normal depth perception cannot see in 3D at all.

“If any person experienced headaches after watching 3 D films, I would not ignore this”, says Dr Shroff, of Shroff Eye Hospital, Mumbai. “It could be a red alert especially in case of children. This is like a ‘screening test’ for some eye conditions which often go undetected like anisometropia (unequal spectacle powers), strabismus (squint) or amblyopia (lazy eye). Many people with minor eye problems, such as a muscle imbalance remain undetected as our brain under normal circumstances adjusts naturally,” said Dr Shroff.  “Some conditions may be congenital, may develop later in life due to systemic diseases such as diabetes, thyroid conditions, myasthenia gravis or due to nerve palsies”.


What is the trick to avoid the headache?

Disregard your experience with 2D movies and stay focussed on whatever is right in front of you; that is what you should be paying attention to. By focussing too long on the background details is what triggers headaches and disorientation.


3 D Digital TV Technology

‘Avatar’ is a 3 D movie made carefully to reduce the earlier 3 D headache – inducing effects! Cameron designed this movie cleverly with smooth and slow moving images. Advanced moviemaking techniques were used to make the images easier on our brain and to allow the brain to keep up with the 3 D illusion.

However, as 3 D moves towards television, we suspect more viewers to have eye problems. Why? Because sports such as football which have quick movements will be even harder to stay focussed on and many more viewers are likely to be symptomatic!

Basically, people need to be aware that if they respond to 3 D in a different way than others, they need to get their eyes checked!

Open your eyes…to a whole new world!

ADVANCES IN CATARACT SURGERY – LIFE-CHANGING RESULTS FOR PATIENTS

Cataract is one of the most commonly known eye conditions causing visual impairment. People who remember when cataract removal involved general anesthesia, days in the hospital, weeks immobile at home and the subsequent need to wear thick glasses may find it hard to believe how much the procedure has changed. Some may be needlessly postponing surgery as a result.

While in the past people waited until a cataract was fully “ripe” and nearly blinding before having it removed, the current recommendation is to have the surgery as soon as a cataract interferes with normal activities, including driving, watching television, climbing stairs, playing games, cooking and reading. In fact, the more advanced a cataract becomes, the more difficult it is to give the desired result.

Every patient’s eye is unique, and surgery must be tailored to the individual

Cataract Surgery can now be customized to reduce and usually eliminate dependence on glasses for distance, intermediate vision and reading

The Evolution of Cataract Surgery-

“No-Stitch” “No Stress” Customized Cataract Surgery

The fundamental aim of cataract surgery, the removal of the opacified natural lens to improve vision, has remained the same for hundreds of years. However, the way in which this is achieved and the expectations of people undergoing the procedure have changed drastically. Advances allow cataract surgery to be customized for every patient.

Today, cataract surgery is nearly always performed under local or topical (eye drops) anesthesia and takes less than 15 minutes.

Microsurgical Techniques

Today the surgery is done through a very small stitch-less, self-sealing incision in the cornea. Earlier this incision used to be 6 mm, then 3 millimeters and now a very tiny incision of 2 mm called Micro Incision Cataract Surgery (MICS). MICS (Micro Incision Cataract Surgery) with stable advanced Intra Ocular lenses helps patients resume work early.

Foldable Advanced Lens Implants

Standard intraocular lenses are monofocal—that is, focused for one distance, usually far. These patients still need glasses for near and intermediate distances. The development of multifocal intraocular lenses offers a further option for patients

“We can reduce drastically, if not eliminate, nearsightedness and farsightedness without the need for glasses or spectacles after the surgery,” said Dr Anand Shroff, Cataract Surgeon, Shroff Eye Hospital, Mumbai. “We discuss in detail the needs, lifestyle and visual demands of the patient alongside the preoperative assessment which greatly helps us plan which implant is most suitable for their needs and expectations. The visual potential of the patient can be realized in many different ways, and when looked at in this context very few cataract procedures are the same”.

Patients now have different options and their surgeries can be tailor-made for them, called ‘Customized Cataract’ surgery, which is customized based on their needs, desire to be free from spectacles and their need to get back to work as soon as possible. Customized matching of lenses covers the entire range of requirements and results in highly satisfied patients.

Many people now do not want to wait for a cataract to occur, but start looking for options to correct both, their reading and distant vision. They opt for ‘PRELEX’ or Presbyopic Lens Exchange even before the cataract starts to interfere with their daily activities. Such options look after all focal points of vision: near, intermediate and distance.

In some people vision is further impaired by rather severe astigmatism, an irregularity of the cornea which makes it difficult for the eye to bring light to a point focus on the retina, no matter how good the glasses you use. So, at the same time that the cataract is removed, the astigmatism can be corrected using new implants called ‘Toric IOLs’.

‘Wavefront Implants’ have taken the cataract lens market by storm.  These are Aspheric Optics which mimic the optics of a ‘young eye’ and give exceptional contrast and night vision.

To aid the eye surgeon get accurate measurements of the lens power, the Zeiss IOL Master is an amazing device. It is engineered as a non-contact optical device that measures the power of the IOL to be implanted. Using partial coherence interferometry, the IOL Master is consistently accurate to within ±10 microns or better. Also, because the IOL Master is non-contact (nothing touches the eye itself), there is no need for anesthesia and there is no potential for spread of contamination or inter-operator variability in measurement.

With the use of accurate diagnostic and measurement tools, combined with very small incisions  and surgeon precision, we have not only delivered stable and exceptional results but also have made our patients extremely satisfied with their outcomes, said Dr Anand Shroff.

Eyesight is one of the most precious gifts that nature has given to mankind. It’s only because of the eyes; one can enjoy the beauty of this world. It’s impossible to imagine life without eyesight.

Though a very small part of body, eye is one of the most complex human organs. It has various parts out of which cornea, lens & retina are the structures mainly responsible for normal vision. Human lens is a transparent structure like a transparent glass which focuses light rays coming from different objects on retina. This is the mechanism of normal vision.

Cataract is a condition in which transparent human lens becomes cloudy like a milky glass. This happens due to normal aging process. Though cataract is seen in old age, it can also occur in young age due to trauma. Rarely it’s seen in children either by birth or during childhood & may or may not be associated with other systemic diseases.

Cataract affects normal vision to a great extent depending upon its grade. All parameters of vision like clarity, colour perception, depth perception, sharpness, contrast are affected badly. This in turn causes lot of disturbances in day to day life of an individual. The only treatment available for this condition is surgery. It can’t be cured by medicines or glasses or any other therapy.

Cataract surgery is most commonly performed surgery all over the world. It has undergone drastic revolutions in last 10-15 years. At present surgery is done by most advanced technique called Phacoemulsification by using a machine (Phaco Machine) through a small 2.8 mm incision. Cataractous lens material is removed with the machine & replaced by artificial high quality foldable Intra Ocular Lens (IOL).Surgery takes hardly half an hour & patient can go home immediately after surgery. No hospitalisation is required. Patient can resume office work after 5 days.

In terms of availability of most modern equipments & advanced surgical techniques, Indian surgeons are at par with Western World. Thanks to advances in Indian Ophthalmology, because of which cataract is no longer a doom for human vision.

Ashwini Eye Care Clinic located at Baner is the centre where this advanced Cataract Surgery is done on routine basis by Dr. Kaushik Shah who is well experienced in this type of surgery. This clinic is well equipped with all the infrastructure & equipments required for modern cataract surgery & provides high quality Cataract & Squint Surgeries on day care basis at affordable rates. All the facilities required for diagnosis & treatment of all the eye diseases are available under one roof including state of the art Operation Theatre & Glass Counter. This centre has become a great help for the patients with eye problems in & around Baner.
