Abstract Details

Purpose:

To analyze the influence of various surgical factors on the post-operative corneal refractive power and astigmatism after keratoplasty in eyes with corneal diseases

Setting:

Faculty of Medicine, Alexandria University, Egypt.

Methods:

Retrospective study of 100 eyes with clear grafts six months following keratoplasty, the influence of different surgical factors (technique of keratoplasty, type of suturing, size of trephination) on the post-operative corneal refractive power and astigmatism was analyzed. All included patients will sign an informed consent.

Results:

Around 70% of the cases of the four subgroups had keratoconus. The flattest 6 months postoperative K readings was the PK with interrupted sutures subgroup with mean 43.90 + 3.09 D. The steepest was the DALK with double running sutures subgroup with mean 45.30 + 1.70 D. The highest 6 months postoperative astigmatism was the PK with interrupted sutures subgroup with mean 7.15 + 1.95 D. The lowest was the PK with double running sutures subgroup with mean 2.36 + 1.15 D.

Conclusions:

Interrupted sutures resulted in significantly higher postoperative astigmatism in both PK and DALK before suture removal. Double running sutures resulted in acceptable postoperative astigmatism even before suture removal FINANCIAL INTEREST: NONE
