ReLEx Small incision lenticule extraction (SMILE), second generation of ReLEx Femtosecond lenticule extraction (FLEx), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism.
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.
Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery , where the cloudy lens is removed to treat a cataract , clear lens extraction is done to surgically correct refractive errors such as ...
While moving the streak or spot of light through the pupil across the retina, the examiner observes the relative movement of the reflex or manually places lenses over the eye (using a phoropter or trial frame and trial lenses) to "neutralize" the reflex. [2] Static retinoscopy is a type of retinoscopy used in determining a patient's refractive ...
The retinotopic stimulation from subretinal implants is inherently more accurate, as the pattern of incident light on the microphotodiodes is a direct reflection of the desired image. Subretinal implants require minimal fixation, as the subretinal space is mechanically constrained and the retinal pigment epithelium creates negative pressure ...
Rosy retrospection is a proposed psychological phenomenon of recalling the past more positively than it was actually experienced. [1] The highly unreliable nature of human memory is well documented and accepted amongst psychologists. Some research suggests a 'blue retrospective' which also exaggerates negative emotions.
Kylie Jenner is treating her past self with kindness.. In her cover story for British Vogue’s “Big Fashion Issue,” the Kylie Cosmetics mogul, 27, opened up about her past cosmetic surgeries ...
Purkinje images are reflections of objects from the structure of the eye. They are also known as Purkinje reflexes and as Purkinje–Sanson images. At least four Purkinje images are usually visible in the normal eye. The first Purkinje image (P1) is the reflection from the outer surface of the cornea. The second Purkinje image (P2) is the ...
