Contact Lens Vision Correction
This is a great alternative for patients who do not want to wear glasses full time.  However, it is important for all patients to have glasses in addition to contact lenses.  There are a variety of different types of contact lenses.  Let’s talk a little about each one. 

 

Soft contact lens (SCL) 

This is by far the most common type of CL.  It is perfect for patients who have an active lifestyle and who is involved in sports.   

There are different types of SLC including daily disposable (where you toss them out after 1 day), daily wear CL (where you take the lenses out every night, but the lenses last from 2 weeks to months depending on the type), and extended wear CL (where you could sleep in the CL.  Wearing schedule will depend on the type as well). 

Depending on what your prescription is and what your needs are, the Doctors will fit you in the best lenses available for your eyes.  New technologies have allowed us to fit patients in spherical lenses, toric lenses for astigmatism, and multifocal CL for presbyopic patients as well.   

 

Rigid gas permeable (RGP) lens 

The main differences between RGPs and SCLs are the comfort and quality of vision.  RGPs are very uncomfortable initially, but once you are adapted to it, the optical quality is much better than that of SCL.  In addition, RGPs are a great alternative for patients who have high prescription either in spherical component or astigmatism. 

Because of its design, RGPs are the most breathable lenses available.  Your cornea needs to have adequate amount of oxygen going through to provide adequate vision.  This is why these lenses are perfect for patients who have had previous corneal complications from SCL overwear. 

Not only does RGPs correct spherical, astigmatism, and presbyopia, specialty RGPs also help treat certain corneal eye diseases such as keratoconus and pellucid marginal degeneration. 

 

Hybrid lenses 

These are the combination of the RGPs in the center with a SCL skirt around.  If you prefer the quality of vision of RGPs and the comfort of SCL, this is the option for you. 

These lenses are available to correct spherical, astigmatism, presbyopia, keratoconus, pellucid marginal degenerations, status post corneal transplant or refractive surgeries such as radial keratotomy.  

 

Corneal refractive therapy (CRT) 

CRT is a specially designed FDA approved therapeutic contact lenses worn while sleeping that reshapes the cornea without permanently altering its physiology. This is a great procedure for patients who is unable to tolerate SCL wear but enjoys an active lifestyle and for patients who prefers not to have surgery but still wants clear vision.  Please consult to see if  you qualify for this procedure.
