LASIK or Lasik (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea.
hide. Eye movement in reading involves the visual processing of written text. This was described by the French ophthalmologist Louis Émile Javal in the late 19th century. He reported that eyes do not move continuously along a line of text, but make short, rapid movements ( saccades) intermingled with short stops ( fixations ).
A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
Myopia, also known as near-sightedness and short-sightedness, [5] is an eye disease [6] [7] [8] where light from distant objects focuses in front of, instead of on, the retina. [1] [2] [7] As a result, distant objects appear blurry while close objects appear normal. [1] Other symptoms may include headaches and eye strain.
Cataract surgery and IOL implantation have the safest and highest success rates of any eye care-related procedures. As with any type of surgery, however, some level of risk remains. Most complications of cataract surgery do not result in long-term visual impairment, but some severe complications can lead to irreversible blindness.
Electroretinography measures the electrical responses of various cell types in the retina, including the photoreceptors ( rods and cones ), inner retinal cells ( bipolar and amacrine cells), and the ganglion cells. Electrodes are placed on the surface of the cornea (DTL silver/nylon fiber string or ERG jet) or on the skin beneath the eye ...
Clear lens extraction (CLE), also known as refractive lensectomy, custom lens replacement (CLR) or refractive lens exchange (RLE) is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery, where cloudy lens is removed to treat cataract, clear lens extraction is done to surgically correct refractive errors ...
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. 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.
