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

• 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

1. Preparation for IOL setting of PC-9 hooking• 10-0 double polypropylene thread (PC-9, Alcon) was

inserted through the cartridge (E1, HOYA).• PC-9 was looped around the haptics of the IOL

(VA70AD or VA65BB, HOYA) by using a cow hitch knot.

Surgical Technique

2. Scleral pockets created at the 2 and 8-o’clock positions

3. Anterior vitrectomy performed4. 2.4-mm scleral corneal incision created at

12-o’clock position

5. IOL setting: IOL and hooked PC-9 loaded into cartridge

6. IOL inserted through incision with injector (ISH-001, HOYA), leaving opposite haptics out of anterior chamber

7. PC-9 looped around haptics8. IOL fixed to ciliary sulcus

BCVA

Surgically induced astigmatism was minimal

Early improvement in BCVA maintained for 1 year

Result 1

Result 2

• Mean endothelial cell density reduced 9.80%• Complications

– IOL iris capture and pupillary block in 1 case– Retinal detachment in 1 case– Cystoid macular edema in 1 case.

Treatments for Complications

• IOL capture– IOL repositioned– Peripheral iridectomy at 6 and 12 o’clock

• Retinal detachment– Scleral buckling surgery– Retina reattached

• Cystoid macular edema – Improvement without medication

Conclusion

• With this technique, visual acuity improved early postoperatively and was maintained for 1 year
