Most cataract procedures today include placing an artificial intraocular lens (IOL) inside the eye. In some cases, though, an IOL cannot be placed. This may happen when the capsule that holds the lens is damaged, or when a secondary surgery to place an implant is not recommended. In these situations, a contact lens worn on the outside of the eye provides the focusing power the eye needs.
Some babies are born with a cloudy natural lens, a condition called congenital cataract. When surgeons remove that lens in infancy, they often leave the eye without an implant because a growing child's eye changes shape and prescription rapidly. A contact lens becomes the primary way these children develop clear vision during critical early years. A 2024 review published in the journal Clinical Ophthalmology found that infant cataract affects 1.5 per 10,000 live births in the United States.
A serious eye injury can damage or dislocate the natural lens. If the lens must be removed and an implant is not a safe option, contact lenses offer a practical path back to functional vision. Our team works closely with surgeons across Las Vegas and Henderson to co-manage these cases from the earliest stages of recovery.
Think of your natural lens like the autofocus mechanism on a camera. Once that mechanism is removed, the camera can still capture light, but the image is blurry. An aphakic contact lens sits on the surface of the eye and bends light in the same way the missing lens used to. Because the eye has lost so much focusing power, aphakic lenses are significantly stronger than a typical contact lens prescription.
Every aphakic eye is a little different. After surgery or trauma, the surface of the eye may have an irregular shape, scar tissue, or a different curvature than a typical eye. Our eye doctors use detailed corneal and scleral topography, a process that maps the entire front surface of the eye in three dimensions, to design a lens that fits precisely. A well-matched fit means better comfort, clearer vision, and healthier tear flow underneath the lens.
For infants and young children, clear input to the brain matters enormously. The visual system develops rapidly in the first several years of life, and a blurry image during this window can lead to amblyopia, sometimes called lazy eye. Fitting an aphakic contact lens early gives the brain the sharp signal it needs to develop strong connections between the eye and the visual cortex.
Soft lenses are often the first choice for infants and young children with aphakia. They are flexible, comfortable, and relatively easy for parents to insert and remove. These lenses come in high-plus powers needed for aphakic eyes and can be replaced on a set schedule. For many pediatric patients, soft aphakic lenses provide a straightforward way to deliver clear vision during the years when the eye and prescription change frequently.
Gas permeable (GP) lenses are made from a firm, breathable material that allows oxygen to reach the cornea, the clear front surface of the eye. Because they hold their shape on the eye, GP lenses can correct irregular astigmatism that sometimes develops after surgery or injury. They deliver crisp optics and are a practical option for older children and adults who need sharper visual quality than a soft lens can provide.
A scleral lens is a large-diameter gas permeable lens that vaults over the entire cornea and rests on the sclera, the white part of the eye. It does not touch the sensitive corneal surface. Instead, it creates a smooth, tear-filled chamber between the lens and the cornea. This design is especially valuable for aphakic eyes with corneal scarring, irregular surfaces, or chronic dryness. Patients across Spring Valley, Enterprise, and Paradise who have struggled with comfort in other lens types often find that scleral lenses provide stable, all-day vision.
For the most challenging cases, where the eye's shape is highly irregular or previous lens designs have failed, our optometrists can use an impression-based fitting system. This technology captures the exact contour of the eye's surface, similar to a dental mold, and produces a lens shaped to match every curve. These lenses are one of a kind and designed for patients who have not found success with standard options.
Standard corneal topography measures only the front central surface of the eye. For scleral lenses and custom designs, our team uses advanced 3D mapping that captures the shape of both the cornea and the surrounding sclera. This gives a complete picture of the eye's surface, which is especially important when fitting aphakic eyes that may have an unusual shape after surgery or trauma.
Anterior segment imaging, a type of cross-sectional scan of the front of the eye, allows our eye doctors to see exactly how a lens sits on the eye, how much space exists between the lens and the cornea, and whether the fit needs adjustment. This level of detail means fewer follow-up visits and a faster path to a comfortable, well-fitting lens.
Some aphakic eyes develop higher-order aberrations, which are subtle optical distortions that a standard lens prescription cannot correct. Wavefront technology measures these distortions in detail, and custom lens designs can compensate for them. The result is sharper, more refined vision, especially in low-light conditions.
The Infant Aphakia Treatment Study, one of the largest clinical trials focused on this condition, followed children who were fitted with aphakic contact lenses after cataract surgery. Results published in the Journal of the American Association for Pediatric Ophthalmology and Strabismus in 2017 found that 95 percent of patients wore their aphakic lenses nearly all waking hours during year one. The study reported 89 percent compliance at the five-year mark. These numbers reflect how well children and families adapt to the daily routine of lens care.
Clinical research supports the use of soft, gas permeable, and scleral lenses for aphakia. Each type offers distinct advantages depending on the patient's age, eye shape, and visual demands. Studies consistently show that contact lenses provide a wider, more natural field of vision compared to aphakic glasses, which tend to magnify images and distort peripheral sight. For most patients, contact lenses remain the preferred optical correction.
Every eye is different, and factors like the cause of lens removal, the health of the remaining eye structures, and the patient's age all influence outcomes. Your eye doctor will help you understand what to expect based on your specific situation.
Your first visit includes a thorough eye health assessment and detailed measurements of your eye's shape and focusing needs. Our optometrists review your surgical history, examine the cornea and surrounding structures, and determine which lens type is the best starting point. For children, this evaluation may involve gentle techniques suited to their age and comfort level.
Once your measurements are complete, our team selects a trial lens and evaluates the fit on your eye. This is the point where the lens is assessed for comfort, movement, and vision quality. Adjustments are common, and some patients go through two or three trial lenses before the final design is chosen. Patients traveling from across Las Vegas, Henderson, or beyond benefit from our structured fitting process, which is designed to minimize the number of visits needed.
Wearing a contact lens on an aphakic eye may feel unfamiliar at first, especially if you have not worn contacts before. Our team provides hands-on training for insertion, removal, and cleaning. For parents of young children, this training is thorough and patient. Most families build confidence within the first week or two and settle into a manageable daily routine.
Your journey begins with a detailed consultation at our Spring Valley office. We review your history, examine your eyes, and discuss your daily visual needs. If you are coming from outside the area, our team can coordinate a streamlined visit schedule to reduce travel.
Using the measurements and imaging from your evaluation, our eye doctors design a lens tailored to your eye. For scleral or impression-based lenses, this step may involve additional scans or molds. The goal is a lens that fits your specific eye shape and delivers the clearest possible vision.
When your lens arrives, you return for a fitting appointment. Our team checks the lens on your eye, confirms the vision is sharp, and teaches you how to handle the lens at home. For pediatric patients, we spend extra time with parents to make sure everyone feels comfortable.
Aphakic eyes, especially in growing children, need regular monitoring. Prescriptions can change as the eye develops, and lenses may need to be updated. Our optometrists at Insight Vision Optometry, Las Vegas schedule follow-up visits to track your progress and adjust the lens design as needed. The Las Vegas desert climate can affect tear film and comfort, so we also evaluate dryness and surface health at every visit.
