Detachments - Post Operative Correction with Contact
detachment of the eye occurs when the retinal layer of the back of
the eye breaks free from the back wall of the eye.
surgical procedure to correct the detachment may involve a scleral
buckle. The scleral buckle acts like a belt around the eye allowing
the detached retina to reattach. The pressure of the buckle causes
the eye to elongate and the prescription changes quite dramatically.
The increase in minus prescription can often be more than -4.00
diopters. Wearing of eyeglasses is prohibitive due to Aniseikonia
- A visual defect in which the shape and size of an ocular image
differ in the two eyes due to uneven prescriptions between the right
and left eyes. The resulting magnification error is minimized with a
proper contact lens fitting for eyes.
some instances of retinal detachment the center vision can be
affected and be not as clear as the good eye. It is still very
important to correct with proper contact lenses to restore Stereopsis - The
ability to see objects in three dimension. Many times post
operatively, patients may only have partial vision across the
retina. It has been clinical noted that even partial sited eyes can
add quite a lot to the capacity of seeing in three dimension. Lack
of three dimensional viewing is very debilitating to many patients
following a retinal detachment.
Some rare cases of retinal detachments
followed by numerous laser treatments can cause severe visual
disturbances called Metamorphopsia. Metamorphopsia - a defect
of vision in which objects appear to be wavy and or distorted
typically resulting from a defect in the retina. There are no lenses
that will correct the visual distortions of Metamorphopsia. In some
the patient can be more comfortable blocking the vision of the
impaired eye as to not affect the good eye. A special contact lens
blocking vision from entering the pupil can be manufactured.
Following retinal detachment surgery
with scleral buckle, everyday events like driving a car and playing
sports can be greatly affected. If the patient had three
dimensional viewing prior the surgery, correction of the eyes with
special contact lenses can be done at any time. Some patients have
experienced return of three dimensional capacity even years after
surgery. Contact lenses can alleviate the difficulty in
producing stereo vision where eyeglasses are insufficient.
can be very debilitating. A contact lens blocking light from entering
through the affected eyes pupil can give great comfort to the patient.
