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

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.
