Astigmatism

7d9db0fa12715c77d37e6983161961eaAstigmatism occurs when the cornea – the clear covering over the eye – is slightly irregular in shape, preventing light from focusing properly on the retina in the back of the eye. With astigmatism some of that light focuses either in front of or behind the retina, resulting in vision that may be blurry for either near or far vision or, for all objects.

Most people have some degree of astigmatism. Eye exams test for the condition and help your doctor provide a proper prescription for eyeglasses or contact lenses. Depending on lifestyle and the degree of astigmatism, some patients prefer to undergo a corneal modification, such as LASIK, to improve their quality of vision.

Presbyopia Correction

Presbyopia is a visual inability of the lens of the eye to focus on object that are close. It occurs when the crystalline lens of the eye loses its flexibility, causing objects to appear blurry. Symptoms make take years to develop and patients begin to show signs of presbyopia in their early – to mid-40s – even in patients who have had laser vision correction.

Presbyopia is not a condition that can be cured. Correction for presbyopia can be made either surgically or nonsurgically.

Nonsurgical

  • Bifocal or progressive reading glasses
  • Reading glasses
  • Multifocal contact lenses

Surgical

  • Conductive keratoplasty (CK)
  • Refractive lens exchange
  • Laser vision correction

Refractive Lens Exchange

Refractive lens exchange (RLE), also known as clear lens extraction, or CLE, is a surgical procedure for vision correction that replaces the natural lens of the eye with an intraocular lens, or IOL. Using the same surgical techniques as cataract surgery, the clear lens of the eye is removed and replaced with an IOL to change the focusing power of the eye.

An alternative to laser vision correction, the RLE procedure avoids the need for a corneal modification that is used during the LASIK procedure, and instead uses the same procedures performed in cataract surgery.

Patients who choose to undergo refractive lens exchange have several options when it comes to the type of IOL that will be implanted into the eye. The RLE procedure uses the same IOLs used in cataract surgery and is able to treat all types of visual disorders, including farsightedness, nearsightedness, presbyopia and astigmatism. Patients are provided with a choice of the most advanced premium IOLs which will allow them to see clearly at all distances.
