Objective To evaluate postoperative outcomes of scleral-sutured ciliary sulcus fixation of foldable intraocular lens (IOL) through a 2.4-mm incision
Methods Subjects: 9 eyes (9 patients) Lens subluxation : 1 eye Aphakia : 5 eyes IOL dislocation : 3 eyes ⇒the lenses were divided in the eye and extracted through 2.4mm incision. Variables examined Best-corrected visual acuity (BCVA) Before and after surgery (1 week; 1, 3, 6, 12 months) Surgically induced astigmatism (SIA) (Cravy method) After surgery (1 week; 1, 3, 6, 12 months) Endothelial cell density Before and after surgery
Surgical Technique Preparation for IOL setting of PC-9 hooking 10-0 double polypropylene thread (PC-9, Alcon) inserted through cartridge (E1, HOYA) PC-9 looped around haptics of IOL (VA70AD or VA65BB, HOYA) with cow-hitch knot IOL cartridge PC9 cow hitch knot
Surgical Technique Scleral pockets created at the 2 and 8-o’clock positions Anterior vitrectomy performed 2.4-mm scleral corneal incision created at 12-o’clock position IOL setting: IOL and hooked PC-9 loaded into cartridge IOL inserted through incision with injector (ISH-001, HOYA), leaving opposite haptics out of the eye PC-9 looped around haptics IOL fixed to ciliary sulcus
Result 1 Early improvement in BCVA maintained for 1 year BCVA (LogMAR)
Result 2 Surgically induced astigmatism was minimal SIA (D)
Endothelial cell density Result 3 Mean endothelial cell density reduced 9.80% Endothelial cell density 2053 1853 pre post (/mm2) 2000 1000
Conclusion Sulcus fixation of an IOL by the injector reduced the number of intraocular actions because of the preoperative preparation for IOL setting of PC-9 hooking. allowed IOL insertion through a small incision. With this technique, visual acuity improved early postoperatively and was maintained for 1 year
