Cataract surgery: symptoms and treatment
A cataract is when the natural lens in our eyes, contained between the iris and the vitreous body, becomes opaque.
There are various types of cataract; all cataracts are due to changes in the chemical composition of the lens (primarily oxidation of lens proteins), which reduces its transparency. There can be many causes for these alterations: the main cause is aging.
A cataract is diagnosed using specific instruments. A full ophthalmology visit is necessary for diagnosis.
The only treatment is cataract surgery. Today, in advanced countries, this generally involves a technique known as phacoemulsification, which fragments the lens using ultrasound. The fragments are then removed and a small artificial lens is implanted. Cataract lens replacement takes place under local or topical anesthesia.
Laser assisted surgery can also be used. A femtosecond laser performs even more precise incisions in the cornea to fragment the lens with less trauma than ultrasound phacoemulsification. It also cuts the capsule that contains the lens more accurately.
Thanks to constant technological progress it is now possible to use intraocular lenses cataract surgery (IOL) that differ in terms of shape, material and size. Such lenses offer different optical power allowing maximum adaptability for correcting a greater variety of sight defects and eye structures.
Choosing the best lens for cataract surgery or most suitable IOL to implant is important for the success of the cataract surgery.
Therefore, the specialist, following a thorough consultation and preoperative exam, will decide whether the patient is a good candidate for cataract surgery and select the best lens for cataract surgery for an optimal result. In cases with the appropriate optical conditions, this can even lead to not needing to wear glasses anymore.
Be sure to ask your ophthalmologist for advice.
