Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic. Phakic intraocular lenses are indicated for patients with high refractive errors when the usual laser options for surgical correction ( LASIK and PRK ) are contraindicated.
Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.
Each aligner is intended to be worn an optimal 22 hours a day for one to two weeks. [6] On average the treatment process takes 13.5 months, [7] although treatment time varies based on the complexity of the planned teeth movements. [6] The aligner is removed for brushing, flossing and eating.
