Trapezoidal relaxing incision for post keratoplasty astigmatism
Ophthalmic Surgery
|February 1, 1986
Summary
Trapezoidal relaxing keratotomy effectively reduced high astigmatism after penetrating keratoplasty. This surgical technique improved vision by significantly lowering the average astigmatism in patients, with no reported complications.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Refractive Surgery
Background:
- High astigmatism is a common complication following penetrating keratoplasty.
- Significant astigmatism can impair visual acuity and quality of life.
Purpose of the Study:
- To evaluate the efficacy and safety of trapezoidal relaxing keratotomy for correcting high astigmatism post-penetrating keratoplasty.
Main Methods:
- Eleven patients with high astigmatism after penetrating keratoplasty were included.
- The study employed a novel surgical technique: trapezoidal relaxing keratotomy.
- Preoperative and postoperative astigmatism measurements were recorded.
Main Results:
- The average preoperative astigmatism was 7.89 diopters.
- An average reduction in cylinder of 5.00 diopters was achieved.
- No surgical complications were reported during the study period.
Conclusions:
- Trapezoidal relaxing keratotomy is a safe and effective procedure for managing high astigmatism after penetrating keratoplasty.
- This technique offers a promising solution for visual rehabilitation in these patients.
