Cataracts and Subluxated Lenses

What are cataracts?

  • A cataract is a clouding of the natural crystalline lens inside your eye. The crystalline lens of the eye is normally highly transparent and helps to focus light on the retina.
  • Symptoms of a cataract can include blurry vision, glare and sometimes distortion.

Procedure information

  • During cataract surgery, small incisions are made into the eye that allow for the cataract to be removed, and an artificial intraocular lens is then inserted to replace it.
  • The procedure generally takes roughly 15-20 mins and is performed under topical or local anaesthesia with sedation.
  • Cataract surgery is performed as a day procedure and patients are dis- charged home following surgery. The first post-operative visit will be the day after surgery.
  • In our experience, the recovery period is relatively pain free and rapid.
  • The patient is required to use eyedrops for a few weeks, and a nighttime shield until the eye is back to normal.

What are Subluxated Lenses?

  • The natural crystalline lens is held in place by tiny fibres called zonules. When these zonules are disrupted or weakened, the crystalline lens or more commonly the artificial intraocular lens may sublux (dislocated) into the back of the eye.
  • Symptoms may include loss of vision, blurry vision or distortion.
  • The treatment involves removal of the subluxated lens and fixation of asecondary intraocular lens.
  • Dr. Sia offers a range of options for secondary intraocular lens implanta-tion including anterior chamber lenses, sutured and sutureless scleral fixated lenses.
