[A comparative evaluation of astigmatic neutrality of 5 mm self-sealing tunnel incision of different types].
The impact produced by incisions of 2 examined types on the corneal refraction was studied in 40 patients (40 eyes) shared between 2 groups according to an incision type. 5 mm tunnel self-sealing incisions of 2 types, i.e. temporal corneal one longer by 3 mm, and upper linear sclerocorneal one stabilized by horizontal suture, were made use of. The obtained refraction was evaluated on week 1 and then in 1 and 3 months after surgery. Group 1 (surgical approach: 5 mm linear sclerocorneal tunnel incision): the mean value of induced astigmatism made 0.68 D during the initial 3 postoperative days, 0.62 D in 1 month after surgery and 0.73 D in 3 months after surgery. Group 2 (surgical approach: 5 mm temporal corneal tunnel incision): the above value made 1.1 D during the initial 3 postoperative days, 0.7 D in one month after surgery and 0.52 D in 3 months.
