Purpose.
To study the relationship between the amount of surgical recession with magnitude and axis of induced astigmatism.
Methods.
From March 2003 to April 2007, 62 patients with intermittent exotropia who had undergone unilateral or bilateral lateral rectus recession were identified retrospectively. The subjects were divided into two groups: group 1 (34 eyes, 34 patients) with a lateral rectus recession ≤9.5 mm and group 2 (56 eyes, 28 patients) with a recession ≤8 mm. Induced astigmatism was defined as the difference between preoperative and postoperative astigmatism, which was calculated using double-angle vector analysis. Cylinder power and axis of induced astigmatism were analyzed at 1 week, 1 month, and 3 months after surgery.
Results.
Larger changes in induced astigmatism were found in group 1 than in group 2 at 1 week after recession (0.8 D cylinder, axis 91° vs. 0.3 D cylinder, axis 88°, Student's t-test, p < 0.01). There was a statistically meaningful correlation between the amount of recession and the cylinder power of induced astigmatism at 1 week after recession (Pearson correlation coefficient r = 0.27, p < 0.01). However, this significant difference between the two groups was not maintained thereafter. Relaxation of astigmatism was observed toward the preoperative value over time in both groups; however, there was a statistically significant difference in the cylinder power of induced astigmatism compared with that of preoperative astigmatism in both groups until the 3-month follow-up (p < 0.01).
Conclusions.
The larger recessions had more induced astigmatism during the first week after surgery. However, there was no statistically significant difference in the magnitude of induced astigmatism thereafter between the two groups. Large lateral rectus recession does not seem to produce a sustained astigmatic change compared with moderate recession.
Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.
I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.
Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.
Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.
Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.
The staff is friendly. The Doc is very knowledgeable. The office is family friendly and everyone is so patient with the little ones.
