Potential LASIK-related applications for the KeraVision technology include treating people with post-LASIK complications such as corneal thinning, undercorrection
and visual regression - that is, cases where prescription inserts might be used to reshape a damaged cornea.
These patients need to know that this undercorrection
may be noticeable in mesopic conditions.
There was consistent undercorrection
after dome osteotomy, with an average alignment of a varus of 1.
, opticians try to stop the eyeball elongating by prescribing a lens that focuses light from distant objects just in front of the retina rather than directly on it.
Why does undercorrection
not reduce its progression?
Some of the risks of poorly performed LASIK surgery include blindness, severe infection, significant undercorrection
, significant overcorrection, severe dry eyes, impaired night vision, double vision, and seeing “halos” and “starbursts.
The use of the Bazett formula results in an overcorrection of the QT interval at higher heart rates and undercorrection
at lower heart rates.
Cyclotorsion in particular can result in misalignment, producing undercorrection
A 2008 American Journal of Ophthalmology report found that 28% of eyes treated with Lasik required additional surgeries less than ten years after the initial surgery due to undercorrection
, overcorrection, or regression.
In a small number refractive eye surgery cases--usually, the patients, who are very young, very near-sighted or very farsighted--overcorrection or undercorrection
of vision occurs.
Cosmetic concerns are one of the most common reasons for undercorrection
Another visual therapy, the See Clearly Method by Vision Improvement Technologies, is built upon the basic principles of Bates but also advocates "progressive undercorrection
," a process that uses steadily weaker prescriptions to blur vision and strengthen the accommodative (focusing) muscles in the eye.
