Prescribing Glasses for Aphakia

Aphakia is the absence of the crystalline intraocular lens. Individuals may develop aphakia as a consequence of a rare genetic disorder, cataract development, or the dislocation of the natural lens. Subsequent refractive options to address aphakia are contingent on the patient's age, the condition's laterality, and the individual's binocular state. Eyecare providers must consider short- and long-term optical strategies to address the symptoms like blurred vision, loss of accommodation, and faded

An uncorrected aphakic eye, characterized by high refractive error and a lack of clear retinal image and sensory input, can adversely affect the development of the visual system.
Cataracts found in children younger than 6 years are likely to cause amblyopia, while those older than 6 years have less risk of more severe forms of amblyopia.
If there is an incomplete correction of aphakia, patients might experience a permanent loss of depth perception; this could increase the likelihood of accidents.

Eyecare providers must consider short- and long-term optical strategies to address the symptoms like blurred vision, loss of accommodation, and faded colors that develop in aphakia.
The affected eye's visual potential and binocular function should be reviewed before offering visual therapeutic options like eyeglasses or contact lenses.
Regardless of lens type, amblyopia treatments should be reviewed and considered if the best-corrected acuity in the affected eye is worse than 20/20.
Anisometropia, or a difference in prescriptions between eyes, is a consequence of unilateral aphakia.
It is generally understood that each 1D of anisometropia corresponds to approximately a 1% difference in relative magnification between the eyes.
The visual system can compensate for about 3% to 5% of relative magnification.
When the relative magnification difference between the eyes exceeds 5%, it can lead to more significant aniseikonia, which often results in patients experiencing intolerance to eyeglass wear.

Due to the optical effects of high-plus spectacle lenses, patients with aphakia may be offered contact lenses or intraocular lens implantation as a first-line intervention.
Eyeglasses may be heavy and difficult to keep on a small child's face; thus, contact lenses are often preferred as the first-line intervention in this age group.
In general, contact lenses are a preferred method of correcting both bilateral and unilateral cases of aphakia.

Ultimately eyeglasses are not the first-line refractive option if visual potential exists in both eyes in a patient with unilateral aphakia.
In these cases, contact lenses or intraocular lenses are offered.
However, eyeglasses might be considered in patients with bilateral or unilateral aphakia and visual potential in one eye with poor vision in the other eye.
Eyeglasses should be avoided when anisometropia exceeds 3.00 diopters of refractive error or 1.50 diopters of astigmatism due to the high risk of aniseikonia.
Children younger than 3 years are poor candidates for IOL placement due to a greater risk of visual axis opacities.
A better option may be to wait until the refractive error has stabilized, typically around the age of 4 or 5 years, before considering IOL implantation.
In trauma cases, contact lenses may offer a level of visual improvement relative to eyeglasses or IOL implantation, given that rigid gas-permeable lenses can mask underlying irregular astigmatism.
