Cataract
What is Cataract?
Cataract is a condition characterized by clouding or opacification of the eye lens. In healthy individuals, the light rays which travel into the eyes get through the pupil and lens and then focused on retina. Our eye lens should be clear enough to focus light precisely onto the retina and if this gets disturbed by a process of clouding,it is termed as Cataract.
Micro incision cataract surgery is one of the latest interventions available to treat cataract. The surgeon will dissolve the cataract and remove it using a computerized instrument which is followed by the replacement of it with a bio-compatible intraocular Lens, ensuring almost natural vision. This surgery is mainly indicated in patients with a visually significant cataract condition, who need to get back to normal routine life style as soon as possible.
The major benefit of micro incision surgery include, early restoration of vision with the ability to get back to daily activities within a short period of time.
How to choose the best IOL?
- Your eyes will be checked and the IOL will be measured before the surgery, using several advanced instruments.
- Now at the Aarna eye care centre with the help of fully automatic devices playing a role in ensuring a high accuracy, better repeatibility and optimization.
- Then your Eye doctor will make you aware about the other options available in order to choose the best IOL for you, depending on your vision (near and long vision) and preference.
- Patients with Astigmatism can go for toric IOLs and other related treatment options.
- Premium IOLs have the capacity to ensure a near perfect vision even without the need of any glasses to be used for distance and near vision, so the best type can be chosen based on the patient’s preference.
Mono-focal lenses
A mono-focal lens is a type of standard intraocular lens which is usually set to see a single distance. Therefore they are usually indicated in patients who have cataracts in both eyes. You eye doctor will check your eyes and choose the best type for you from the ones which are designed for near focus (reading, stitching, knitting), mid-distance focus (grocery store shelves, personal computers) and distant focus vision (watching television, driving).
Multifocal lenses
This is one of the latest types of IOL which significantly lowers or removes the requirement for using glasses and contact lenses.
However, it is better if one can go for IOL implantation in both eyes, to reach the maximum vision possible.
Important to Remember
- Multi focal IOLs have the complete potential of eliminating the need of wearing glasses with few exceptions such as people with disorders in the retina. Further more, some patients will also need glasses when reading small printed texts, reading in dim lights etc.
- The success rate of IOLs depends on the proper preoperative work up and selecting the right type of multifocal IOLs.
