Tailored Contact Lenses for Your Unique Eyes
Contact lens exams require more than standard vision testing. These specialized evaluations include precise measurements of your cornea’s curvature, pupil size, and tear film quality. Dr Diana Risco & Associates performs thorough assessments to determine the best lens type for your unique eye shape and lifestyle needs.
Our eye doctor begins with a complete eye health examination, checking the cornea, iris, lens, and retina for any conditions that might affect safe contact lens wear. We then take detailed measurements using advanced diagnostic tools like keratometers and corneal topography to map your eye’s surface. This information helps us select lenses that fit comfortably and provide clear vision throughout your day.
Understanding the Fitting Process
Proper contact lens fitting involves multiple steps to achieve optimal comfort and visual clarity. We use specialized equipment to measure corneal curvature, which determines your lens base curve. The diameter measurement typically falls between 13 and 15 millimeters, though even small variations significantly impact fit.
Our eye doctor evaluates several critical factors:
- Tear film quality and quantity for adequate lens moisture
- Pupil and iris dimensions to prevent light distortion
- Corneal topography showing your eye’s unique contours
- Eye muscle coordination and overall ocular health
- Current vision needs based on work and lifestyle activities
Trial Lenses and Follow-Up Care
After gathering measurements, we place trial lenses on your eyes to assess their interaction with your tears and corneal shape. Our eye doctor observes lens movement and alignment through a slit lamp microscope. You’ll wear these trial contacts for one to two weeks before returning for evaluation.
Follow-up appointments check for:
- Corneal changes or surface damage from lens wear
- Proper lens positioning and comfortable movement patterns
- Visual acuity improvements with your new prescription
- Any discomfort or dryness requiring lens adjustments
- Long-term fit stability for safe daily use
Most people can successfully wear contacts, including those with astigmatism or mild dry eyes. We provide complete instructions on insertion, removal, and proper lens care for healthy vision.
Why Digital Retina Imaging Changes Everything
Digital retina imaging captures detailed photographs of the back of your eye using specialized cameras. This non-invasive technology produces high-resolution color images of your retina, optic nerve, and blood vessels. At Dr Diana Risco & Associates, we use this advanced diagnostic tool to detect eye conditions early, often before you notice any symptoms.
The procedure takes just minutes and causes no discomfort. Our eye doctor may apply dilating drops to widen your pupils, though many modern systems work without dilation. You’ll rest your chin and forehead on supports while looking straight ahead. A brief flash captures the images, which appear instantly on a computer screen for review.
Catching Eye Problems Before They Affect Your Vision
Early detection makes treatment more effective for many eye conditions. Digital retina imaging reveals problems like glaucoma, macular degeneration, and diabetic retinopathy in their earliest stages. Our eye doctor can spot tiny changes that might indicate developing issues.
The technology provides benefits that traditional examination methods cannot match:
- Wide-field views show up to 82% of your retina in one image
- High-resolution photos reveal small abnormalities and subtle changes
- Electronic storage allows comparison between visits over years
- Detailed images help track how treatments are working
- Visual documentation makes it easier to understand your eye health
What Your Retinal Images Can Reveal
Your retina contains the only blood vessels a doctor can view directly without surgery. These vessels serve as windows into your overall health. Changes in retinal blood vessels can signal systemic conditions like hypertension, diabetes, or high cholesterol before other symptoms appear.
Our eye doctor examines your images for signs of various conditions:
- Retinal tears or detachment requiring immediate attention
- Fluid buildup indicating macular degeneration
- Damage to the optic nerve from glaucoma
- Blood vessel changes from diabetes or high blood pressure
- Abnormal growths or lesions needing further evaluation
We recommend annual digital retina imaging as part of complete eye care. Regular imaging helps us monitor changes and maintain your vision health long-term.
See the Difference a Thorough Eye Exam Makes
Comprehensive eye exams go far beyond simple vision screenings. These thorough evaluations assess your complete eye health through multiple noninvasive tests. Dr Diana Risco & Associates performs detailed examinations that check visual clarity, eye coordination, internal structures, and disease indicators. Each test provides valuable information about your eyes and overall wellness.
Many serious eye conditions develop without warning signs. Glaucoma, macular degeneration, and diabetic retinopathy often progress silently in early stages. Regular comprehensive exams catch these issues before permanent damage occurs. Our eye doctor uses advanced diagnostic equipment to identify problems you might not notice on your own.
Protecting Your Vision Through Early Detection
Routine comprehensive exams serve as your first line of defense against vision loss. These appointments can reveal early signs of over 250 different systemic health conditions. Changes in your retinal blood vessels may indicate diabetes, hypertension, or high cholesterol before other symptoms appear.
Adults aged 18-60 benefit from exams every two years, while those over 60 need annual visits. Our eye doctor will recommend the right schedule based on your age, family history, and risk factors. Key preventive benefits include:
- Catching glaucoma before irreversible optic nerve damage occurs
- Identifying macular degeneration in treatable early stages
- Detecting diabetic retinopathy before it affects your sight
- Monitoring changes in your prescription for clearer vision
- Reducing long-term treatment costs through early intervention
What Happens During Your Complete Evaluation
Your comprehensive exam includes multiple specialized tests. We start by discussing your medical history, current medications, and any vision concerns. Visual acuity testing measures how clearly you see at various distances using the standard eye chart.
The refraction test determines your exact prescription using a phoropter. Our eye doctor will ask you to compare different lens options to find the clearest view. Additional evaluations examine:
- Eye muscle coordination and movement patterns
- Pupil response to light and peripheral vision range
- Internal eye structures using slit lamp microscopy
- Intraocular pressure to screen for glaucoma
- Retinal health through dilated pupil examination
