Abstract
Purpose:
This study was performed to analyze the safety (complications) and the improvement of surgery procedure in penetrating keratoplasty with blepharophimosis by adjustable sclera-fixation double ring.
Methods:
Study design: retrospective study<br /> The incidence of postoperative ptosis was compared between adjustable sclera-fixation double ring (n=10) and normal sclera-fixation double ring (n=10) , both were used during penetrating keratoplasty. Patients were randomly selected.<br />
Results:
Under topical anesthesia, sclera-fixation double ring could be easily applied without damaging levator muscle of the palpebral, and sutured 4 points by 7-0 vicryl (polyglactin 910). This achieved excellent scleral fixation of the eye globe and facilitated suturing and improve safety during surgery. During the penetrating keratoplasty, surgery was performed with complete fixation of cornea in center, and prevent collapsing of eye globe. In adjustable sclera-fixation double ring, the incidence of post-operative ptosis was significantly lower than normal double ring.(p<0.01)
Conclusions:
Adjustable sclera-fixation double ring was useful for patients with narrow ocular fissure to improve safety and prevent postoperative ptosis during penetrating keratoplasty.
