New Achievements On Cataract Surgery

The past years have witnessed the great achievements in cataract surgery

. At the beginning, a large cut will be made to cure the problem- this will lead a great void in the eyes. Therefore, some special eyeglasses are need if receivers want to see clearly of objects. And there are still some contact lenses that can be used after the surgery.

However, wearing glasses and lenses is too bothersome and there arises post cataract implant. In order to rectify distance vision, intraocular implants are firstly developed. Later, implants for near vision also become possible.

As there are over several millions of people who will receive cataract surgery each year- this will be double in the near future, some advanced alternatives are needed. Crystalens developed by Bausch and Lomb is considered as the most promising alternative for both distance and near vision problems in the future. It is completely different from traditional multifocal implants- they can automatically adjust according to peoples needs. However, it must be naturally work like natural lens- that can be changed when people see objects at different distance. This surgery is proved perfect in many aspects- it can ensure rather ideal distance and near vision.

Of course, crystalens must work together with cilliary body in the eyes. This part can pull the lens to a needed thickness by changing its shapes. This tissue is also proved very important after the surgery- the crystalens must be attached to the tissue for better function.

When cilliary body contracts, it will change in shape, so as to offer the implant lenses an ideal thickness. And the greater the cilliary body moves, the larger the diopters will be. In addition, crystalens allow much greater flexibility in the eyes, for more free eye movement.

Usually, different crystalens have different optic zone. Though most of them work well, there are still some cases of weak near and nigh vision. Luckily, the latest HD series offering much better thickness is proved for ideal near vision.

This new series are proved nice by FDA. They are also nice for poor night vision.
