SSOME MODERN ASPECTS OF CATARACT TREATMENT IN CHILDREN
The authors represent their own results of surgical treatment of cataract in children with implantation of various types of intraocular lenses: common Corneal, torus — AcrySof Toric and aspheric — AcrySof IQ. It was established, that post-surgical visual

Smart soft contact lenses for continuous 24-hour monitoring of intraocular pressure in glaucoma care
Continuous monitoring of intraocular pressure remains a grand challenge in glaucoma care. Here the authors develop smart soft contact lenses for continuous 24-hour monitoring of intraocular pressure in human eyes, even during sleep.

Introduction: This report describes a case of elevated intraocular pressure following the use of 0.125% atropine eye drops in a child wearing orthokeratology lenses. Case Presentation: A 9-year-old boy presented to our clinic with myopia, and he had been

Influence of the theoretical model eye on the numerical evaluation of fractal intraocular lenses [PDF]
In this work we present the numerical evaluation of a new design of fractal intraocular lens studied through a ray-tracing program. To determine the monochromatic and polychromatic performance of these lenses in different theoretical model eyes the Modulation Transfer Function (MTF) and the area above the MTF (AMTF) have been used.

Designing Covalent Organic Framework-based Light-driven Microswimmers towards Intraocular Theranostic Applications [PDF]
Even micromachines with tailored functionalities enable targeted therapeutic applications in biological environments, their controlled motion in biological media and drug delivery functions usually require sophisticated designs and complex propulsion apparatuses for practical applications.

A new trifocal corneal inlay for presbyopia [PDF]
Corneal inlays (CIs) are the most recent surgical procedure for the treatment of presbyopia in patients who want complete independence from the use of glasses or contact lenses. Although refractive surgery in presbyopic patients is mostly performed in combination with cataract surgery, when the implantation of an intraocular lens is not necessary, the ...

A Data-Driven Model with Hysteresis Compensation for I2RIS Robot [PDF]
Retinal microsurgery is a high-precision surgery performed on an exceedingly delicate tissue. It now requires extensively trained and highly skilled surgeons. Given the restricted range of instrument motion in the confined intraocular space, and also potentially restricting instrument contact with the sclera, snake-like robots may prove to be a ...

AGEs in human lens capsule promote the TGFβ2-mediated EMT of lens epithelial cells:Implications for age-associated fibrosis [PDF]
Proteins in basement membrane (BM) are long-lived and accumulate chemical modifications during aging; advanced glycation end-product (AGE) formation is one such modification. The human lens capsule is a BM secreted by lens epithelial cells. In this study,

Hybrid Robot-assisted Frameworks for Endomicroscopy Scanning in Retinal Surgeries [PDF]
High-resolution real-time intraocular imaging of retina at the cellular level is very challenging due to the vulnerable and confined space within the eyeball as well as the limited availability of appropriate modalities. A probe-based confocal laser endomicroscopy (pCLE) system, can be a potential imaging modality for improved diagnosis. The ability to
