The choice of treatment depends on how severe the cataracts are and how much they are affecting the child's vision.
In children with
mild cataracts, surgery might not be required and treatment may include glasses, eye patching (of the normal eye, to prevent lazy eye in the eye with cataract) or eye drops.
However, if the
cataract affects the child's vision, then surgery is required.
Surgery involves the removal of the cataract to allow for clear vision.
In very young children (<2 years old), it may not be possible to insert a lens implant, and they may require either special (aphakic) glasses or contact lenses to see clearly.
In older children, a man-made lens implant may be inserted in the eye at time of surgery. Having an implanted lens means that they may only require regular powered glasses rather than high-powered thick aphakic glasses.
After the surgery, the child will be watched closely for problems such as infection and increased eye pressure. Subsequently, long-term care includes monitoring the development of the child's vision (Eg. with glasses, contact lenses, patching as required), other problems like increased eye pressure, posterior capsular opacification (cloudy film behind lens implant after surgery that can cause cloudy vision) and retinal detachment.
However, it is possible for a cloudy film to grow on the bag (lens capsule) and cause your vision to be more cloudy. This is called posterior capsule opacification (PCO), which may occur months or years after surgery. It can be cleared with a 5 minute, painless laser treatment (YAG Capsulotomy) that is done in the clinic.
Infant A was found to have a white reflex or ‘white eye’ (white-colored reflection of the eye is seen when light is shone on the eye; as compared to reddish pink-colored reflection normally) in his right eye during his visit to the doctor. The doctor found a white cataract on his eye check, which was affecting his vision.
He went for surgery to remove the white cataract at 3 months old. After the operation, he was fitted with contact lens for his right eye. His mother diligently ensured to put on the right eye contact lens every day and patched his left eye (the other normal eye) 4-6 hours per day, to encourage the development of his right eye’s vision.
At 12 years old, his vision was 6/6 in his left eye (normal vision) and 6/9 in the right eye (2 lines on Snellen’s chart from normal vision). Fortunately, he did not have any problems such as glaucoma (high eye pressure), retinal detachment and amblyopia (lazy eye due to poor development of the right eye’s vision). At 13 years old, a man-made lens implant was placed in his right eye, so that he does not need to wear contact lens anymore.
Child B had poor vision (6/36 on Snellen’s chart) during her Kindergarten year 1 eye screening. Her doctor found lamellar cataracts (a form of cataracts in children) in both eyes. There were no other eye or general health problems found.
