Presbyopia, also termed as ‘lao hua yan’ is an expected consequence of aging process. In the young eye, the soft and flexible crystalline lens changes its shape to focus on near objects in a process called ‘accommodation’. However, with age, the lens loses its elasticity therefore decreasing the ability of the eye to focus on near objects. This is a sign of the beginning of cataract. So if you start feeling that your ‘arms are too short’, you are not alone.
The most common correction method is prescriptive glasses. When presbyopia begins, people who already wear glasses may either require another pair of glasses for near work (reading glasses) or switch to lenses that allow them to see objects at different focal length such as bifocal or progressive addition lenses. Bifocal lenses contain 2 distinct points of focus in the same lens whereas progressive lenses offer a gradual visual transition from distant to near objects.
Presbyopes who are contact lens wearers may either consider wearing reading glasses on top of their contact lenses when doing near work or switch to multifocal or monovision contact lenses.
A cataract is a misting or opacity of the natural crystalline lens of the eye. It prevents light from entering the eye and causes a dimness of vision. If the cataract is allowed to progress without treatment, vision can be seriously limited. As cataract is a slow progressing disease, many patients do not realize that their cataract have started to develop. Yellowing or misting of the natural lens in the eye may start developing at the age of 40.
Most cataracts are the result of the body’s natural ageing process, though some may be the result of injury to the eye. Rarely, cataracts can occur in infancy due to abnormal development of the eye.
Neither eye drops nor oral medications can cure cataract. Cataract surgery is the only effective treatment that improves the vision of the patients with cataract. It involves removal of the cloudy natural lens in the eye and replacing it with a clear artificial lens, called an intraocular lens (IOL).
The EyeClinic offers advanced cataract surgery in Singapore to get rid of the blur and opacity that can hinder proper eyesight.
Modern cataract surgery in Singapore and almost everywhere else is generally safe. However, as with all other surgical procedures, there are potential complications. These complications are uncommon, but may limit the success of the surgery when they occur. Some of the possible complications include:
PCO is treated with a fast and painless outpatient procedure called yttrium-aluminum-garnet (YAG) laser capsulotomy. In this procedure, a laser beam is used to remove the hazy posterior capsule from your line of sight. This allows the surgery to be performed without any incision and patients may go home after surgery without any dressing.
