Purpose: This current study was conducted to investigate the influence of the variable techniques available for corneal suturing on visual outcomes in PKP.
Methods: In this prospective study 40 cases underwent penetrating keratoplasty which were divided according to the technique of suturing into 2 groups each of 20 patients; first group that underwent continuous suturing and the second group underwent interrupted suturing and they were followed up along 1 year postoperative for BCVA, IOP, and both topographic & refractive astigmatism.
Result: The results of the study showed comparable improvement between the two techniques regarding the BCVA, refractive astigmatism and topographic astigmatism along the 12 months of follow-up. The need for readjustment was higher in the cases underwent interrupted suturing.
Conclusion: there were no significant visual or refractive differences between patients operated with continuous & interrupted suturing techniques though the patients of the interrupted technique needs more suture manipulation for favorable outcomes than that needed in continuous technique patients
