Newly designed self-retaining contact lens for vitreous surgery

Outcome of primary rhegmatogenous retinal detachment using microincision vitrectomy and sutureless wide-angle viewing systems

“…In this study, we report the results of a retrospective analysis on the repair of primary RRD through sutureless MIVS with the use of a noncontact sutureless WAVS. The noncontact sutureless WAVS have several advantages over the hand-held irrigating lens systems or the self-irrigating fixed contact lens retaining ring system [12]. The noncontact sutureless WAVS does not require an experienced assistant to hold the lens in place, thus the risk of excessive pressure on the cornea, causing corneal epithelial defect or edema, is avoided.…”

“…However, corneal surface dehydration and lens condensation could significantly decrease the visibility of the fundus image, and this requires occasional irrigation of the corneal surface or cleaning of the front lens [12, 13]. With BIOM (Oculus Surgical, Inc), Merlin (Volk Optical, Inc.) and OFFISS (Topcon Medical Inc.) noncontact WAVS, focus is achieved by moving entire lens support system up and down to adjust the distance between the cornea and front lens.…”

Self-Retaining Contact Lens Simplifies Intravitreal Injection Course in Rats

“…Because the inferior surface curvature approximately matches the curvature of the anterior corneal surface of rats, the refractive power of the cornea would be compensated without planishing the cornea and then the image resolution and stereopsis would be also improved, using the same principle as that used in the Chalam KV’s prism lens [ 5 ]. In terms of stability, the new-designed lens is made of a high refractive acrylic material instead of quartz or optical crown glass, which gives the lens a weight advantage as it is lighter than 0.05 g, allowing the self-containing lens to attach to the cornea firmly with the aid of the viscoelastic material.…”
