SING IMT in pseudophakic eyes: Results of the first experiences.

ABSTRACT:

Purpose

To evaluate the feasibility and outcomes of implanting the Smaller-Incision New-Generation Implantable Miniature Telescope (SING IMT) in pseudophakic patients affected by late-stage dry AMD.

Subjects

Five pseudophakic patients' eyes with stable dry AMD were suitable for SING IMT implantation. Four eyes were excluded because of previous YAG laser capsulotomy. Patients underwent preoperative assessments, including visual acuity measurements and OCT scans.

Methods

Surgical procedures were performed under peribulbar anesthesia, with careful IOL removal and SING IMT implantation. Postoperative follow-up was conducted at regular intervals to monitor visual acuity, device positioning and complications.

Results

Postoperative outcomes demonstrated improvements in visual acuity for most patients with an average gain in CDVA (Corrected Distance Visual Acuity) and CNVA (Corrected Near Visual Acuity) of 16,8 ± 10,2 and 13,8 ± 7,4 ETDRS letters, respectively. Limited complications have been observed. In one case, we observed dislocation of the device into the vitreous chamber, which we managed through vitrectomy and scleral fixation of the SING IMT using GoreTex suture.

Conclusions

Despite being traditionally contraindicated for pseudophakic patients, SING IMT implantation in selected cases yielded favorable outcomes, indicating potential benefits for this population. Further research with larger sample sizes and longer follow-up periods is warranted to refine patient selection criteria and optimize surgical techniques.

Project description:BackgroundTotal aniridia after ocular trauma without disruption of the intraocular lens (IOL) has been reported in patients with a history of small-incisional cataract surgery. We report one case each of total and partial aniridia after accidental falls experienced by two elderly Japanese women.Case presentationsCase 1. A 76-year-old woman with a history of small-incisional cataract surgery more than 10 years previously fell onto concrete and had a contusion that affected the left side of her face. At the initial visit, the best-corrected visual acuity (BCVA) was hand motions and the intraocular pressure (IOP) was 38 mmHg in her left eye (OS). A blood clot was present in the well-formed anterior chamber and expulsed iris tissue was seen beneath the conjunctiva. Exploratory surgery showed no scleral laceration other than the previous sclerocorneal tunnel. After hyphema removal, total aniridia and an intact in-the-bag fixed IOL were seen. By 4 months, the BCVA was 1.2 and the IOP was 13 mmHg OS.Case 2An 88-year-old woman with a history of small-incisional cataract surgery more than 10 years previously had a fall that resulted in right-sided zygomatic and maxillary bone fractures. The BCVA was light perception and the IOP was 29 mmHg in her right eye (OD). Exploratory surgery showed no scleral laceration and the previous sclerocorneal tunnel was found; iris strand prolapsing from the sclerocorneal tunnel was seen. After hyphema removal, partial iris loss and an intact lens position were seen. By 1 week postoperatively, the BCVA was 0.05 OD and the IOP was 12 mmHg OD.ConclusionsIt has been postulated that previously created small-incision tunnels can function as release valves during blunt trauma by preventing further global rupture and limiting IOL prolapse or retinal injury. Our cases suggested this can happen even long periods after cataract surgery. The case with partial aniridia demonstrated the process of the expulsive aniridia, and its findings do not contradict the postulated mechanisms.
