Purpose:
|
our aim is to investigate the astigmatic power, axis and spherical equivalent (SE) after strabismus surgery using power vector analysis according cycloplegic refraction.
|
Methods:
|
we prospectively recruited 51 patients (93 eyes) referred for strabismus surgery. Epidemiologic data such as age,sex and clinical data like cycloplegic refraction, amount of deviation, type of surgery , muscle surgery, SE, JO (vertical & horizontal astigmatism) and J45 (oblique astigmatism) extracted from files . Postoperatively all measurements repeated at1, 3 and 6 months and compared with pre op data using SPSS
|
Results:
|
51 patient were recruited into study and underwent different surgeies.SE significantly decreased after surgery for the first, third and sixth months following surgery (P=0.0001).In all groups JO showed significant changes at the 1 month following surgery (P=0.0001).J45 did not change significantly postoperatively in all groups. There was significant difference in the magnitude of changes in SE one and three month following surgery (P=0.0001).There were no significant difference between sex groups in SE and JO changes (P>0.05)
|
Conclusion:
|
Strabismus surgery in strabismus patients tends to induce a statistically significant change in with the rule astigmatism and myopic shift in SE .This stigmatism change seems to remain within the 6 months following surgery.
