are there any special lenses for correcting diplopia? can it be corrected by surgery?

Question

The diplopia occured after surgery for retinal detachment

Answer 1

Diplopia is not uncommon after retinal detachment surgery. The causes are either:
1) reposition or adhesion in the extraocular muscles after a scleral buckling proceedure. or 2) Shifting of the macula or preferred locus or retinal fixation due to a malposition of the detached retina.

Surgical realignment of the eyes is a viable alternative in cases that are stable and where there exists a potential for central fixation and where no tortion is involved.
Conversely, correction by prism may work for small deviations but once again torsional diplopia is very difficult to correct.

The bottom line is that your primary ophthalmologist should be consulted in regards to your particular case.

Answer 2

Diplopia is corrected by " Prismatic lens" as against spherical lens for routine refractory errors.As time passes more and more powerful prisms will be needed.Surgery can not correct diplopia caused by surgery.
Oter steps of help are 1) magnifying images using a computer 2)using one eye at a time and 3)increasing illumination.
