Scleral lens prescribed for dry eye, on a removal plunger. Scleral lenses are removed using the fingers, or a small lens removal plunger. Lenses are then cleaned and sanitized before reinsertion. Scleral lenses cannot be worn while sleeping and many wearers sanitize their lenses overnight.
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.
Cataract surgery is the most common application of lens removal surgery, and is usually associated with lens replacement. It is used to remove the natural lens of the eye when it has developed a cataract, a cloudy area in the lens that causes visual impairment. [4] [10] Cataracts usually develop slowly and can affect one or both eyes. [4]
Nucleus emulsification makes it possible to aspirate the particles through a very small incision. After removing all hard central lens nucleus material by emulsification, the softer outer lens cortex is removed with suction only. After nuclear cracking or chopping (if needed), the cataract is emulsified and aspirated. The nucleus or fragments ...
Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath the conjunctiva where it is absorbed.
The glued IOL technique consists of making two partial-thickness, approximately 2.5 mm by 2.5 mm, scleral flaps exactly 180° apart, followed by a sclerotomy with a 20-gauge needle 1 mm from the limbus. A 23-gauge vitrectomy cutter is introduced from the sclerotomy site, and a thorough vitrectomy is done to remove all the vitreous tractions. A ...
