About: Shroff Eye Hospital is India’s First Eye Hospital that the Joint Commission International (International Division of JCAHO, USA) has given accreditation for excellence in patient care and health care delivery. Shroff Eye is also India’s first and only Wavelight Concerto 500 Hz LASIK center- The Worlds Safest and Fastest LASIK.
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.
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.
