Abstract

PURPOSE
To compare the short-term clinical outcomes of transscleral fixation intraocular lens (IOL) with two haptics or one haptic.
METHODS
We retrospectively reviewed the medical records of 26 patients with transscleral fixation of IOL (11 with one-haptic fixation, 15 with two-haptic fixation) except in patients whose visual acuity is not expected to improve due to retinal problems or ocular trauma. We analyzed the manifest refraction, visual acuity, refractive error preoperatively and postoperatively, preoperative IOL decentration, operating time, and postoperative complications.
RESULTS
When comparing the two groups preoperatively, the mean lens decentration in the one-haptic group was 2.73 ± 2.88 mm and 4.59 ± 2.18 mm in the two-haptics group. The decentration in the two-haptic group was greater than in the one-haptic group, but not significantly. Visual acuity and refractive power were not significantly different between the groups. The mean operation time (minutes) was 65.00 ± 22.69 and 93.66 ± 29.54 in the one-haptic and two-haptic groups, respectively. The operation time in the one-haptic group was significantly shorter than in the two-haptic group (p = 0.020). When comparing visual acuity preoperatively and postoperatively, both groups showed significant improvement (p < 0.01). However, refractive error and postoperative IOL decentration were similar between the groups.
CONCLUSIONS
The short-term surgical results of transscleral fixation using the two surgical techniques were not different; one-haptic transscleral fixation was preferred due to shorter operation time and lower patient discomfort.

  Figure 1. Steps of two-haptic transscleral fixation of intraocular lens (IOL). (A) Scleral flap is created at two sites. (B) A long curved double-armed 10-0 polypropylene needle is passed through the scleral flap site. (C) A 25-gauge syringe is passed from the opposite site and docked the curved needle. (D) The docked 25-gauge syringe and curved needle are moved from the scleral flap. (E) A 3.0 mm corneal incision is created at the temporal side and the 10-0 polypropylene is pulled through the corneal incision site with a Sinskey hook and is cut. (F) The 10-0 polypropylene is tied on both haptics of the IOL.

  Figure 2. Steps of one haptic transscleral fixation of intraocular lens (IOL). (A) Scleral flap is created at one site. (B) Double-armed 10-0 polypropylene needle is cut in half, pushed through the end of the 25-gauge hollow syringe tip and the syringe is placed through the scleral flap site. (C) A 3.0 mm corneal incision is created at the temporal side and the 10-0 polypropylene is pulled through the corneal incision site. (D) The 10-0 polypropylene is tied on a one side of the haptic of the IOL.
