  • Once the crystalline lens is removed-that is, once the capsular bag is empty-it no longer has any reason to exist. (crstodayeurope.com)
  • For these reasons, the capsular bag seems to be an inadequate location for accommodating IOLs, mainly due to the fibrosis and atrophy that occur after crystalline lens removal. (crstodayeurope.com)
  • Lens luxation (or dislocation) can be associated with various processes that can weaken or damage the zonular-capsular complex. (aao.org)
  • Upon detailed eye examination, which began with Visual Acuity, it showed that vision loss was because of cloudy lens i.e. she had developed moderate cataract (Anterior capsular cataract along with Nuclear Sclerosis Grade II) mainly due to her age. (rnreyecare.com)
  • The capsular bag was dilated, diaphanous with clear anterior and posterior capsule without any evidence of capsular fibrosis or opacification. (bvsalud.org)
  • The exam was most notable for something we saw in the right eye-a large dense hexagonal brown mass in the anterior chamber consistent with a dislocated crystalline lens nucleus ( Fig. 1 ). (aao.org)
  • Documentation by previous eye providers had labeled Mr. Grover as aphakic in the right eye, suggesting that the lens dislocation happened years ago or around the time of the accident, with the nucleus initially falling into and resting in the vitreous cavity. (aao.org)
  • Later, after the lens had been reposited into the posterior chamber, (2A) slit lamp showed the anterior chamber without the mass, and (2B) indirect biomicroscopy ophthalmoscopy with a 20-D lens showed the crystalline lens behind the iris. (aao.org)
  • In order for accommodating IOLs to have a future in cataract surgery and presbyopia correction, we must determine, once and for all, the best location for these lenses. (crstodayeurope.com)
  • In simple terms, a cataract is usually part of the normal aging process that changes the natural, clear lens of the eye into a cloudy, opaque structure that inhibits or diminishes the passage of light to the retina. (sunetra.co.in)
  • A cataract is simply the clouding or discoloration of the lens. (sunetra.co.in)
  • Light passing through the cataract (or cloudy lens) is blocked or distorted and results in a blurred or dimmed image on the retina. (sunetra.co.in)
  • Because cataract surgery involves removal of the focusing lens of the eye, a replacement lens must be used if the patient is to see well following surgery. (sunetra.co.in)
  • Subsequently, Shabnam had an investigation for lens power calculation called as IOL Master as she decided to undergo cataract treatment. (rnreyecare.com)
  • The high molecular weight proteins found in cataractous lenses produce outflow obstruction in experimental perfusion studies similar to that found in phacolytic glaucoma. (medscape.com)

  • he evaluated her eyes and explained that the hazy vision in her eyes was because of the cloudy lens. (rnreyecare.com)
  • A device emits ultrasonic energy on the cloudy lens that breaks the lens into small pieces, which are then removed by suction. (rnreyecare.com)
  • Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. (lookformedical.com)
  • The nu-cleus appeared to be tethered by a clear membrane consistent with a torn lens capsule that extended from behind the pupil. (aao.org)
  • With this finding, we diagnosed lens luxation into the anterior chamber. (aao.org)
  • [ 4 , 5 , 6 ] Although a macrophagic response is typically present, macrophages are believed to be a natural response to lens protein in the anterior chamber rather than the cause of the outflow obstruction. (medscape.com)
  • The possibility of 2 forms of phacolytic glaucoma was proposed in a recent report: (1) a more acute presentation caused by rapid leakage of lens proteins that occlude the trabecular meshwork and (2) a more gradual presentation with macrophages resulting from an immunologic response to lens proteins in the anterior chamber.

  • Given all of the technologies and treatments we have at our disposal to correct refractive errors and treat patients with cataracts, it is a wonder that we have not yet conceived an accommodating IOL design that perfectly mimics the movement of the natural crystalline lens. (crstodayeurope.com)
  • C ataracts are an opacity or clouding of the normally crystalline lens of the eye caused by the natural aging process, metabolic changes, injury, various forms of radiation, toxic chemicals, and certain drugs. (sunetra.co.in)

  • Normally the focusing lens of the eye is crystal clear, allowing light to pass through and form a clear image on the retina. (sunetra.co.in)
  • The working of eye's lens is similar to that of camera's lens, which is to focus light properly so that image can be viewed clearly. (rnreyecare.com)
  • All we would need are lenses to focus the light and a fiber to guide it. (turismoassociati.it)
  • Mrs. Khan opted for a multifocal lens (a lens which allow clear vision for near as well as far without glasses).In Phacoemulsification, a micro incision is made on the side of the cornea. (rnreyecare.com)
  • With evidence of an accommodative effect of certain lenses now available, there may be future potential for these lenses. (crstodayeurope.com)
  • The question remains: Will we ever succeed in creating an IOL that reproduces the mechanisms of the ciliary body and crystalline lens?There have been reports of objective and subjective evidence showing the accommodative amplitude of certain IOLs, 1,2 but, in order to get to the bottom of this issue, we must first review the basic principles of accommodating IOL designs. (crstodayeurope.com)
  • The available evidence implicates direct obstruction of outflow pathways by lens protein released from microscopic defects in the lens capsule that is intact clinically. (medscape.com)
