Authors refer about the effect of adjusting (adjustment of the
suture tension) of the running corneal
suture on the final cylindrical refraction in patients who underwent
penetrating keratoplasty due to
keratoconus. In our article we evaluate two groups of patients. The group I consists 76 patients (76 eyes) who regularly visited our department of ophthalmology. There were 52.6% of females and 47.4% of males. The average age at the time of surgery was 33.5 +/- 5.2 years (range, 18-52 years). In this group of patients, the adjusting was performed during the surgery. In the group II 35 patients (40 eyes) underwent the adjusting procedure of the running corneal
suture in the early postoperative period. There were 19 (54.0%) women and 16 (46.0%) men. The average age of the whole group at the time of surgery was 34.6 +/- 3.8 years (range, 18-50 years). The indication to carry out the adjusting was topographically verified
astigmatism of more then 3.5 cylindrical diopters (D cyl). The purpose of this study was to find the ultimate surgery technique to get not only the clearness and good healing of the corneal graft, but first of all to prevent extensive
ametropia already during the surgery. In the early stage after the surgery we are trying to reduce emerged
refractive error and to get faster recovery of good visual acuity of the operated eye. In the sense of the least final postoperative
astigmatism, the best results we have reached in cases where the donor corneal graft was 0.25 mm larger in diameter and the
suture was adjusted during the surgery using light circles according to Serdarevic. In this group of patients the average final cylindrical
refractive error after the surgery was 2.00 +/- 0.81 D cyl. When adjusting the corneal
suture in postoperative period, the mean final
refractive error decreased of about 3.09 +/- 1.62 D cyl.
