What is cataracts? Why do they occur?
The natural ageing of the crystalline lenses inside the eye is called a cataract. This lens gradually loses transparency as it ages, and becomes cloudy or opaque.
When do they typically appear?
This can vary greatly from person-to-person. From the age of 45 onwards, most people will begin to have “tired eye” or Presbyopia Loss of focus power The lens will then begin to gradually lose clarity.
What are the signs and symptoms of cataracts
Patients usually notice a decrease in sharpness of their vision. Photophobia The prescription for their glasses may also change frequently. The symptoms can vary depending on which type of cataract you have.
What is the treatment for cataracts?
The only treatment that is effective for cataracts at the moment is surgery. The procedure involves the removal of an old natural lens and its replacement with a synthetic intraocular lens (IOL). Under local anaesthesia, eye drops are used (topical anaesthesia). The operation takes about 10 minutes, and it is almost painless. In general, the recovery process is quick, and excellent results are achieved in a matter of days. But, timeframes may vary according to each case.
What are the expected benefits?
The recovery of a patient with no other eye disorders is often spectacular. The recovery of a patient with other eye conditions will also be affected by these factors. Moreover, modern multifocal intraocular lenses The use of lasers to correct presbyopia can produce excellent results. Patients are often able to gain a full range and even eliminate the need for reading glasses (for distance).
What are the recent advances?
The development of multifocal lenses for intraocular lenses is the biggest breakthrough in recent years. These allow surgeons to correct presbyopia and other refractive errors – such as myopia (short-sightedness), hypermetropia (long-sightedness), and astigmatism – During the treatment of the cataract, the lens can be treated.
Is it correct that you must wait for the cataract to “ripen”, before undergoing surgery?
No. It’s the exact opposite. The more the lens ages and becomes dense, the more complicated and traumatizing the surgery may be. If the rest of the eye structures are in good health, it is recommended that the cataract be operated on once the patient has noticed a decrease in vision.
