Cataracts and Lens Disorders

Dr. Leung addresses primary treatment involves surgical removal of the cataract and implantation of an artificial intraocular lens (IOL).

• Secondary Cataracts (Posterior Capsular Opacification): Clouding of the posterior lens capsule that can occur months or years after cataract surgery.
• Age-Related Cataracts: Clouding of the eye's natural lens that occurs as part of the aging process, leading to blurry vision, glare, and difficulty seeing at night.
• Congenital or Pediatric Cataracts: Clouding of the lens present at birth or developing in early childhood.

Glaucoma Management

Dr. Leung addresses a group of eye diseases that damage the optic nerve, often characterized by increased intraocular pressure, leading to progressive, irreversible vision loss.

• Normal-Tension Glaucoma: Optic nerve damage and vision loss occur despite intraocular pressure being within the normal range.
• Congenital or Childhood Glaucoma: Symptoms can include excessive tearing, light sensitivity, and an enlarged cloudy cornea.
• Angle-Closure Glaucoma (Acute or Chronic): A type of glaucoma where the drainage angle of the eye becomes blocked, leading to a sudden (acute) or gradual (chronic) rise in eye pressure.

This list is not exhaustive. For a comprehensive evaluation of your eye health, a consultation with Dr. Andrea Leung is necessary.

• Advanced Technology Intraocular Lenses (IOLs): Includes toric IOLs for astigmatism correction and multifocal/EDOF IOLs for a range of vision.
