Intracorneal ring implantation is a promising new treatment for patients with early to moderate PMD and who are intolerant of contact lenses. The main aim of the Pellucid project is to develop a platform based on the multi-agent technology for assisting public employees in their organization. No intraoperative and postoperative complications occurred. Aragorn Technologies is an open data intelligence platform providing users with data analysis and visualization capabilities. No patients lost any Snellen lines of BCVA. At the third postoperative month, refractive stability was obtained. Mean postoperative spherical equivalent was -1.52 (range, -7.25 to +1.87 SD, 3.01).

At the last postoperative examination, 6 eyes (75%) had a BCVA > or =20/25 mean postoperative refractive astigmatism was -2.53 (range, -4.50 to -1.25 SD, 1.03).

Uncorrected visual acuity improved in all 8 eyes (100%). The minimum follow-up was 12 months (range, 12-42 months standard deviation, 14.14). Changes in corneal shape were evaluated by corneal tomographic maps. Preoperative and postoperative uncorrected visual acuity, best spectacle-corrected visual acuity (BSCVA), refractive astigmatism, and spherical equivalent were assessed. The diagnosis was supported by Orbscan II tomography (Bausch & Lomb). This abstract was presented at the 2019 ARVO Annual Meeting, held in Vancouver, Canada, April 28 - May 2, 2019.To evaluate the use of the intracorneal ring (ICR Intacs, Addition Technology, Inc., Fremont, CA) for the treatment of pellucid marginal degeneration (PMD).Įight patients with PMD who were intolerant to contact lenses received ICR segments in the superior cornea (0.25 mm thickness) and in the inferior cornea (0.45 mm thickness). the Pellucid project, an important part of quality assessment process is. Longer follow up and larger sample size are needed to confirm our findings. Pellucid Technologies Private Limited is an Strike Off company established on with its office registered at F-24, L.G.F., Lajpat Nagar-Ii, New Delhi Dl 110024 In and has been running since 12 years 11 months with a paid up capital of 1.00 lakh.

ISACS is a safe, effective and inexpensive method for management of PMD, with advantages of customized shape (ring segment, crescent shaped), width and arch length. No significant side effect or complication was observed during the nine month follow up period. Implanted ISACSs were clear and stable on the day after implantation and thereafter on all examinations during the follow up period. The steep areas were displaced superiorly and the amount of irregular astigmatism was reduced on topography (included Figure). Uncorrected visual acuity and best-corrected visual acuity was improved after surgery in all eyes on all examination.īoth myopia and astigmatism were reduced in all cases and were stable during 9 months follow up.

The arc lengths, width and shape were determined based on the area of inferior steepening. Dimensions of the implanted ISACS were ring shaped with width of 2 mm and arc length of 160,and 210 degree in two eyes and crescent shaped with maximum width of 3mm and arc length of 180 degree in two eyes.The Thickness of all segments were 350 micron. A new handmade spatula was used for implantation (will show in video).

A femtosecond laser-assisted stromal canal 4 mm in width was created in the 5.5 to 9.5 mm corneal zone.Īn ISACS was implanted in the canals. In this prospective study, we implanted allograft Intrastromal corneal segment (ISACS)in four eyes of 3 patients with PMD as a new surgical procedure. In the current pilot study we introduce a new surgical method for management of thinning and high irregular astigmatism due to PMD. cases were diagnosed as keratoconus and 6 as pellucid mar- ginal degeneration. There is no universally accepted method for managing these patients, especially subjects who cannot wear any type of contact lens.

Management of pellucid marginal degeneration (PMD) is a subject of ongoing research in the field of corneal ectasia.
