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.
