As a result of their special qualities,Lucent Skin Eye Cream toric lenses are sometimes more expensive. People with a mild astigmatism might avoid the extra expense by just using ordinary contact lenses. The cornea will to some extent conform to the shape of the lens and minimize the scattering of light. In fact, toric lenses may not be necessary at all for mild astigmatism. Only your eye doctor can say for certain after administering an exam.For people end up needing toric lenses, there are many options available. You can purchase single or multifocal lenses. Toric lenses are also available in the same types as regular lenses--disposable, single day wear, weekly wear, monthly wear, and even extended wear.

Photorefractive keratectomy, or PRK, is the first laser procedure that used the Excimer Lasers to reshape the cornea. During PRK, some of the surface cells on the cornea, called corneal epithelium, are removed prior to the delivery of the treatment. Like LASIK surgery, PRK can correct farsightedness, nearsightedness, and astigmatism.As for who is a good candidate for PRK, this would depend on the anatomy of eye. In particular, patients whose cornea is deemed to be too thin or too weak to undergo a flap procedure such as LASIK would do best with PRK.

Patients that undergo the PRK procedure will have a longer recovery time. This is due to pain and discomfort that usually lasts several days. In addition, these patients will not have the quick recovery of vision that LASIK patients experience.Normally it takes up to a week to recover one's vision.LASIK has received a lot of good reviews from those who have had it. However, patients have reported having the same success with PRK that they had with LASIK, so the decision as to what type of procedure to choose is up to the doctor and the patient. 

The initial consultation will help establish the best course of action based on various factors surrounding the condition of the patient's eyes.LASIK, or laser in-situ assisted keratomileusis, is an outpatient procedure that uses a cool laser beam of ultraviolet light to reshape the cornea, the clear outer covering of the eye. The laser removes microscopic layers of tissue to change the curvature of the cornea and correct common vision errors such as nearsightedness, farsightedness and astigmatism.
