2. Scleral lens - Wikipedia

   en.wikipedia.org/wiki/Scleral_lens

   Scleral lenses may be used to improve vision and reduce pain and light sensitivity for people with a growing number of disorders or injuries to the eye, such as severe dry eye syndrome, microphthalmia, keratoconus, corneal ectasia, Stevens–Johnson syndrome, Sjögren's syndrome, [1] aniridia, neurotrophic keratitis (anesthetic corneas), complications post-LASIK, higher-order aberrations of ...

3. Contact lens - Wikipedia

   en.wikipedia.org/wiki/Contact_lens

   Scleral lens, with visible outer edge resting on the sclera of a patient with severe dry eye syndrome. A scleral lens is a large, firm, transparent, oxygen-permeable contact lens that rests on the sclera and creates a tear-filled vault over the cornea. The cause of this unique positioning is usually relevant to a specific patient whose cornea ...

4. Glued intraocular lens - Wikipedia

   Both the haptics (blue color) are externalized under the scleral flaps. They will be tucked into scleral pockets and fibrin glue applied to seal them 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 ...

6. Manual small incision cataract surgery - Wikipedia

   en.wikipedia.org/wiki/Manual_small_incision...

   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.

7. Effects of long-term contact lens wear on the cornea - Wikipedia

   en.wikipedia.org/wiki/Effects_of_long-term...

   Long-term contact lens use can lead to alterations in corneal thickness, stromal thickness, curvature, corneal sensitivity, cell density, and epithelial oxygen uptake. . Other structural changes may include the formation of epithelial vacuoles and microcysts (containing cellular debris), corneal neovascularization, as well as the emergence of polymegethism in the corneal endoth
