    Abstract: The present disclosure pertains to the phakic refractive lenses such as toric lenses, an advanced posterior chamber floating phakic refractive lens (PRL) designed for the correction of severe refractive errors, including myopia, hyperopia, and astigmatism. This innovative lens can reduce or minimize complications commonly associated with traditional phakic intraocular lenses, such as intraocular pressure elevation, cataract formation, and iris pigment dispersion. The phakic refractive lenses such as the toric lenses described herein feature a buoyant, flexible structure with a central aperture to facilitate aqueous humor flow, creating a natural centering force that stabilizes the lens within the pupillary space.
