Comparison Of Two Different Intrascleral Intraocular Lens Flanged Fixations: Double Haptic Flanged Fixations And Four- Point Suture Flanged Fixations

To Compare two different intraocular lens implantation techniques: haptic-flanged intrascleral and four- point flanged intrascleral fixations.

Aier eye Hospital of Wuhan University, Wuhan Hubei Province, China.

According to the surgical method, they were divided into 2 groups: haptic-flanged group(group 1) and four-point flanged group(group 2). Surgical time, preoperative and postoperative parameters were recorded . The tilt and decentration of IOL were measured after 1 moth of the surgery using CASIA2.

The group 1 contained 42cases (42 eyes), and thegroup 2 contained 34cases (34 eyes). The surgical time of group 1 is significantly shorter than that of group 2, and the comparison between the two groups is statistically significant (t=-6.372, p < 0.01). There was no statistically significant difference in IOL tilt and decentration between the two groups (t=0.176, p=0.862; t=-0.870, p=0.394). Complications associated with both surgical methods were minimal and no statistically significant difference. Haptic breakage(4.76%) , haptic disinsertion(2.38%) ,flange slippage(2.38%) and Iris-optic capture(4.76%) only occured in group 1. The incidence of Flange exposure was 4.76% in group 1 and 5.88% in group 2.

 Both surgical methods are minimally invasive and less complicated IOL fixed surgery.  haptic-flanged  fixation technique's procedure should be faster. Doctors can choose the appropriate surgical method based on their own surgical experience.
