Each iteration of the Sierpinski triangle contains triangles related to the next iteration by a scale factor of 1/2. In affine geometry, uniform scaling (or isotropic scaling [1]) is a linear transformation that enlarges (increases) or shrinks (diminishes) objects by a scale factor that is the same in all directions (isotropically).
In 2022, a retrospective study conducted on 82 eyes with OOKP using original Strampelli technique, showed an anatomical survival of 94% up to 30 years of follow-up. The same study also reported a visual acuity better than 1.00 logMAR (or 20/200 Snellen) at 10 years in 81% of the eyes, and a visual acuity of 1.21 logMAR (or 20/324 Snellen) at 30 ...
Those considering laser eye surgery should have a full eye examination. Although the risk of complications is decreasing compared to the early days of refractive surgery, [32] there is still a small chance for serious problems. These include vision problems such as ghosting, halos, starbursts, double-vision, and dry-eye syndrome. [33]
The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the ...
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. [1] Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage.
System: Eye and visual system: Significant diseases: Cataract, retinal disease (including diabetic retinopathy and other types of retinopathy), glaucoma, corneal disease, eyelid and orbital disorders, uveitis, strabismus and disorders of the ocular muscles, ocular neoplasms (malignancies, or cancers, and benign eye tumors), neuro-ophthalmologic disorders (including disorders of the optic nerve)
n November 1954, 29-year-old Sammy Davis Jr. was driving to Hollywood when a car crash left his eye mangled beyond repair. Doubting his potential as a one-eyed entertainer, the burgeoning performer sought a solution at the same venerable institution where other misfortunate starlets had gone to fill their vacant sockets: Mager & Gougelman, a family-owned business in New York City that has ...
In many East Asian countries, double eyelid surgery is the most popular surgery, especially in South Korea. Depending on the methods, directing doctors' experience, and the difficulty of the individual case, this surgery can cost between about US$2,000 to $4,000. The procedure is famous for producing double-eyelid for patients for the long-term.
