To assess docking capability, suction and corneal distortion with new Liquid Optics Interface 12 in patients with palpebral fissures widths ≤ 25 mm.
: National University Health System, Singapore
19 eyes were docked with a new size-optimized 2 piece Liquid Optics Interface 12 (LOI-12) on a system for laser cataract surgery (Catalys, OptiMedica, Sunnyvale, CA). Patient fissure widths from lateral to medial canthus were tabulated. The first step of docking consisted of application of the non-applanating suction ring. Docking technique and centration were noted and compared to the standard-sized Liquid Optics Interface. Difficulty achieving suction was noted. After suction was achieved, patients were asked to apply force to the interface by moving eye in all directions and by shutting eyelids. This enabled testing of the docking and suction quality. Any cases of suction loss and suction break were noted. The suction ring was then captured with a disposable lens that was attached to the system. Full volume 3D OCT was used to acquire images of the anterior segment through the posterior capsule and customised treatment subsequently done.
Suction was successfully achieved in all cases. No patients complained of amaurosis during the course of treatment. All had complete capsulotomies performed with stable and secure suction. No corneal folds were identified. Seven patients had arcuate incisions created and 8 patients had the cataract incisions created.
The new LOI-12 is optimised for treatment in all patients with small palpebral fissures. Its non-applanating interface avoids inducing corneal folds. Surgical options included the primary cataract incisions, sideports, arcuate incisions, capsulotomy as well as segmentation and softening of the cataract prior to cataract surgery.
