Capsulotomy (BrE /kæpsjuː'lɒtəmi/, AmE /kæpsuː'lɑːtəmi/) [1] is a type of eye surgery in which an incision is made into the capsule of the crystalline lens of the eye. In modern cataract operations, the lens capsule is usually not removed.
Psilotum is a genus of fern-like vascular plants.It is one of two genera in the family Psilotaceae commonly known as whisk ferns, the other being Tmesipteris.Plants in these two genera were once thought to be descended from the earliest surviving vascular plants, but more recent phylogenies place them as basal ferns, as a sister group to Ophioglossales.
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.
In some cases post operative tear secretion and dry eye syndrome have been observed along with similar post operative complications seen in LASIK surgery. [1] [6] Like PRK and LASEK, SMILE prevents the flap-related risks for example in contacts sports. [8]
The condition of posterior staphyloma in high myopia was first described by Scarpa in the 1800s. [6] Speculation about reinforcement of the eye began in the 19th century, when Rubin noted that sclera reinforcement “is probably the only one of all the surgical techniques [for myopia] which attempts to correct a cause, rather than an effect”. [7]
As a result, intorsion of the eye is still possible. It also provides sensory anesthesia of the conjunctiva , cornea and uvea by blocking the ciliary nerves . This block is most commonly employed for cataract surgery , but also provides anesthesia for other intraocular surgeries.

Tenon's capsule (/ t ə ˈ n oʊ n /), also known as the Tenon capsule, fascial sheath of the eyeball (Latin: vagina bulbi) or the fascia bulbi, is a thin membrane which envelops the eyeball from the optic nerve to the corneal limbus, separating it from the orbital fat and forming a socket in which it moves.
