Pune: Cataract patients now can hope for spectacle free life post-surgery. The developing technology in the field of intraocular lens (IOL) has proved to be a boon and it has been one of the solutions which has helped in restoring the sight of millions of people world over suffering from cataract.
Cataract accounts for over 62 per cent of blindness in people older than 50 years in India and with India being home to over 80 lakh blind people, cataract poses as one of the biggest healthcare challenges for the country.
Speaking on IOL, Dr Jeevan Ladi, Founder, Dada Laser Eye Institute, Pune, said that with modern technology, eye care has witnessed a shift from restoring vision to improving quality of vision.
“Using IOLs, such as monofocal and multifocal lenses, not only it is now possible to restore vision but also with the latest extended range of vision IOL technology, improved vision clarity and reduced dependency on spectacles post-surgery have become a real possibility. The objective has been to provide options that help patients experience life better,” said Ladi.
He further added that the challenge is not small, but for the persistent efforts of authorities and the eye surgeons in the country, things are changing for the better.
“For combating cataract, with 6,78,908 cataract surgeries in 2016 under the National Programme for Control of Blindness (NPCB), Maharashtra has surpassed the target of 4,56,011 surgeries,” said Dr Ladi.
With a high success rate in cataract surgeries all over the world, the ability to restore vision is not the foremost interest area anymore. The focus has shifted to ensure the quality of life by enhancing the quality of vision post-surgery for patients.
Ophthalmologist Dr Vaishal Kenia said that with IOLs replacing the old, cataract lens, the quality of vision has improved considerably post-surgery. Up till now, monofocal lenses were the most commonly used IOLs during cataract surgery.
“However, being monofocal, the lenses deliver an improved vision for only one focal point. Usually, they are used for ensuring distance vision and glasses are prescribed for near vision. In comparison, multifocal IOLs provide better near vision. However, chromatic aberration, halos and glares and reduced night-time vision clarity limit the quality of life
post-implant. The latest IOL technology with extended depth-of-vision resolves and mitigates these issues,” said Kenia.
He also added that as compared with monofocal lenses, the extended range of vision IOLs provides high quality vision across a range of distance to about 26 inches away with seamless transition across day and night.
“The new IOLs also correct the chromatic aberration, enabling a better contrast and functioning. Also, the continuous band of vision, provides the vision for all distances,” said Kenia.
