Four-point fixation contributes to decreased astigmatism after deep lamellar keratoplasty

Abstract

Abstract:

BACKGROUND: Deep lamellar keratoplasty has been widely used in the surgical treatment of keratoconus, which can increase the visual acuity similar to penetrating keratoplasty and has a low incidence of graft rejection.
OBJECTIVE: To explore whether four-point fixation can effectively reduce postoperative astigmatism after deep lamellar keratoplasty.
METHODS: A retrospective analysis was performed in 50 patients (50 eyes) with keratoconus who received deep lamellar keratoplasty. Intraoperative four-point fixation was performed in 25 cases (25 eyes) and direct cutting of the planting bed in another 25 cases (25 eyes). Postoperative astigmatism and simulated keratoscopy reading were compared between two groups.
RESULTS AND CONCLUSION: All the patients were followed up for 6-12 months, an average of 8.3 months. There were no corneal graft rejections, infections, and secondary glaucoma in the two groups postoperatively. Postoperative astigmatism and simulated keratoscopy reading were better in patients undergoing the four-point fixation. These findings indicate that the four-point fixation technique is shown to effectively reduce postoperative astigmatism caused by eye deformation, bed distortion, and decreased intraocular pressure in deep lamellar keratoplasty.
