Implantation of Synthetic lenses in eye may be safer than laser surgery when it is to be implemented to improve short sightedness. Surgery without risk is impossible and chances are there to develop a cataract. Eyes not able to focus fine on objects at a distance, because the image projected by the lens comes into focus before it reaches the retina.

This tendency is short sightedness. The image received by brain is hazy. Glasses and contact lenses can improve short sightedness, but in case of the patient very short sighted there may be very thick and heavy lenses to be used. Laser operation has become a widely accepted way to treat short sight. It principle of working is by reducing the tissue at the front of cornea.

Even though laser operation generally works well, few people imply with poorer sight than they had before. But the new operation inside eye in being introduced named phakic intraocular lens surgery. It is like placing a contact lens at the back of cornea. The scientists have also assumed that the dissimilarity between light and dark was transparent for people doing phakic intraocular lens surgery.
