Abstract Details

Purpose:

To describe a novel technique for the surgical management of aphakia

Setting:

Hospital del Salvador, Universidad de Chile, Santiago de Chile

Methods:

We describe the results of this technique for the surgical management of aphakia. It involves the injection of a foldable hydrophobic acrylic intraocular lens, which haptics have been pre-threaded with Gore-Tex, through a 2.4 – 2.75 mm incision. The lens is then secured to the scleral wall of the eye through two pair of opposing sclerotomies at the sulcus level

Results:

We registered 25 patients from January 2017 to August 2018, which mean age was 42 years (range 4 – 85 years old) and mean following time was 4.5 months. We clasified the aphakia cases in post-trauma cases (60%) o non traumatic cases (40%). 85% patients gained 2 or more lines of best corrected visual acuity and 15% (3 cases) kept or lost visual acuity. We had 5 cases of postoperatory complications: 3 cases of cystic macular edema, 2 cases of IOL tilt and 1 case of persistent uveitis.

Conclusions:

This technique provides excellent tilt and torque control due to its 4-point fixation at the same horizontal plane, maintains a sutureless incision similar to phacoemulsification surgery, with very low induced astigmatism, and allows for centration fine-tuning using the Purkinje reflexes, even after the implantation has been completed. We have standardized this surgical technique for the past 2 years for aphakia correction, ranging from post-trauma cases, lensectomies and complicated cataract surgeries without capsular support. We believe this to be a very safe and effective technique for the surgical management of aphakia with a very flat learning curve
