Cataract Lens

Eye surgeons started in recent months a series of operations to implant adjustable cataract lenses depending on the light (Light Adjustable Lens).

They have the ability to change their shape when a certain intensity laser beam is projected on them, which means that these lenses can be “designed” according to the needs of patients and may be used by patients suffering from cataract myopia, hyperopia or astigmatism.

Adjustable lens according to light can be implanted in the eye and their rigidity and degree of curvature can be modified outside the eye, using a computer.

If you notice that your sight is impaired lately, do not hesitate to go to an ophthalmologist. Only your healthcare professional can determine exactly what it is: if you have cataracts, another disease that results in loss of vision, or simply need to change your glasses.

At the end of the consultation, the doctor will know to tell you what type of cataract you have and if it is operable or not. If you have cataracts but the sight is still good, the doctor will call you to regular checks (at an interval of about six months) to track the progress and to determine the optimal time of surgery (for surgery to receive the most modern approach and have the maximum chance to recover the default vision).

A very old cataract is often accompanied by complications or risks. You should know that, independently of the evolutionary stage of cataract, postoperative results depend on the health of the retina, vitreous and optic nerve at the time of surgery. After complete preoperative evaluation, your doctor will explain exactly what to expect after cataract surgery.

Artificial lens inserted into the eye must have a certain number of diopters and. Based on the biometrics; the doctor will prescribe a “recipe” for buying an artificial lens. Regarding glasses for distance, it is difficult to say in advance whether or not you need them. This depends on the existence of defects in glasses before the cataract operation.

In any case, if you were the bearer of glasses before surgery, the lens will not match after the surgery. But a new pair can only prescribe the proper healing after surgery – after about two months. If one eye had had cataract surgery and the other not – there will probably be diopters difference between the two eyes. But the doctor who follows you will know what to do and you will be able to prescribe the right glasses. After cataract surgery, the natural lens is removed and replaced with an artificial one. So, the new lens has no accommodative ability and the patient will have to wear glasses for reading.

Cataracts can be diagnosed by a doctor even if early phase. There is no treatment that can prevent or stop the growth of cataracts.

Artificial lens has parameters that cannot be selected and optional parameters.

Optional parameters of foldable lens:

1. Higher degree of folding at 60 MI.

2. Blue filter (light blue is considered to be harmful to the macula).

3. Crystalline aspheric foldable (in the case of descentration bag is not affected by the contraction or when the pupil is in mydriasis).

4. Crystalline multifocal – allows for distance and near.

5. Crystalline pseudoacomodation – allows for the distance and made a small accommodative.

Today cataract operation can be done through incisions of 1.6 mm, which controls the fluid pressure in the eye.

Cataract surgery can be performed on an outpatient basis with local anesthesia or topical anesthesia only (drops).
