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 which is a lining of light-sensitive cells bordering the back of the eye. Our eye lens should be clear enough to focus light precisely onto the retina and if this gets disturbed by a process of clouding, your eye doctor will diagnose it as Cataract.
Micro incision phacoemulsification surgery is one of the latest interventions available to treat cataract. The surgeon will dissolve the cataract and remove it using acomputerized instrument which is followed by the replacement of it with a bio-compatible intraocular Lens, ensuring a near natural vision. This surgery is mainly indicated in patients with avisually significant cataract condition, who need to get back to normal routine life style as soon as possible.
The major benefit of micro incision phacoemulsification include, early restoration of vision with the ability to get back to daily activities within a short period of time, which is usually around 48 hours.
Few decades back before intraocular lenses (IOLs) were introduced, before IOLs people had to wear glasses with thick lenses or customized contact lenses following the surgery in order to gain a clearer vision. Since this became quite a burden to carry out day to day activities and poor vision quality, the need of IOL implants came in to the subject and now you can enjoy an excellent quality ofvision with these latest Intraocular lenses, designed using a advanced technology.
IOLs which are made up of flexible and foldable material are around one third of a coin and mimics the action of a natural lens. The light rays falling on to the IOL are focused on the retina and travelled through the optic nerve to the brain, thereby ensuring a better visual outcome. However, similar to how you are going to get a pair of glasses, it is important to get your eyes checked by an ophthalmologist before hand, in order to get prescribed with the most suitable IOLs, to obtain the fullest visual potential.
Now you can benefit all these facilities at the Global Eye Clinic with the help of fully automatic devices playing a role in ensuring a high accuracy, better repeatibility and optimization.
Traditional cataract surgery which has been prevailing over decades, mainly focus on the correction of both eyes for distant vision where most patients will have to use reading glasses for near vision, after the surgery.
A mono-focal lens is a type of standard intraocular lens which owns an excellent fixed focal value, 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).
However, this particular correction of vision through Mono-focal intraocular lenses should not to be misinterpreted as 'Mono-vision’, which is a separate entity where one eye would be operated for distant vision while the other is corrected for near vision.
This is one of the latest types of IOL which significantly lowers or removes the requirement for using glasses and contact lenses. In fact, this carries several prescriptions all in one lens.
Multi focal lenses are designed with a series of focal sections or rings embedded in the lens and based on the initial point where light rays are directed from, the individual will be able to see both near and far away objects clearly.
However, it is better if one can go for IOL implantation in both eyes, to reach the maximum vision possible.
This is a special type of mono focal IOL which is indicated in patients with Astigmatism-distortion or blurring of vision related to both near and distant objects.
As far as the requirement for glasses is concerned, most patients might need them in order to acquire a near perfect vision.
However, ones who do not want to wear glasses can go for an additional treatment called ‘limbal relaxing incisions’, which can be done during the cataract surgery or separately. In this surgical technique, small erincisions (after a specific calculation), made on the cornea will help to create a more rounder and symmetrical shape.
