Simple & Straightforward

Getting started is easy – no diagnostic fit set is required for most Metro Optics GP lens designs.

Note: Keratoconus can be fit empirically, but chair time is reduced by using a diagnostic set. We offer a complimentary ComfortKone Quick Fit Set. Learn more here.

Order GP lenses empirically, without any lens design calculations. Simply send the following patient information to consultation.

Exam Information

  • Corneal Topography
  • Keratometry Readings (Auto-K works well)
  • Manifest Refraction
  • Pertinent Patient History (surgery, trauma, past contact lens wear)

This information helps us understand the corneal shape & curvatures we are attempting to fit. If you don’t have a topographer, that’s okay!

What Information Do You need to order an InSight Scleral Lens?

Our methodology focuses on simplicity and optimizing your chair time. Provide us with your observations, and we’ll handle the lens parameters.

If you can place a diagnostic lens on the eye with sodium fluorescein (NaFl), note your observations, we can deliver an initial lens within a few days.

Corneal and scleral GP lenses typically take 2–3 days to manufacture; Hydra-PEG adds one day to the process. Standard shipping is 2-3 business days.

Checklist for Simplified Ordering:

1. Initial Lens Selection
Based Selection on Sagittal Height
This reflects the overall curvature of the cornea.

  • Steep/Ectatic Corneas: Start with the Prolate 5.000 SAG
  • Flatter/Oblate Corneas: Select the Oblate 4.750 SAG

2. Evaluation (Three Steps)

  1. Central Clearance:
    Aim for ~250 microns of clearance, represented by a 1:1 ratio—250 microns of post-lens tear film and 250 microns of lens center thickness.
  2. Peripheral Clearance:
    Ensure NaFl clears the limbus 360° with 50–80 microns of peripheral clearance. Look for any areas of bearing or blanching; the limbus should always be vaulted.
  3. Edge Alignment:
    The lens should sit comfortably on the conjunctiva. Check for signs of impingement or blood vessel constriction.

    Please send images or short 2-3 second videos of the lens on the eye.

    Quick Tip:
    After lens removal, check for staining and report it to consultation if present.

3. Patient Feedback

Ask the patient how the lens feels:

  • Lens Awareness: If the patient feels the lens, it’s likely a landing issue.
  • Discomfort: If the lens is uncomfortable, remove it immediately. Scleral lenses should be very comfortable.

4. Topography:

Provide topographical data for consultation—it gives a clearer picture for customized lens fitting.

5. Anterior Segment OCT (Optional):

If available, AS-OCT images offer additional data to help understand what is happening with the lens on the eye, though it is not required.

6. HVID (Horizontal Visible Iris Diameter):

This measurement is essential for incorporating multi-focal optics, optimizing visual acuity and customizing the lens to the patient’s lifestyle.

7. Sphere-Cylinder Over-Refraction:

The SCOR provides the most accurate visual acuity and avoids inducing astigmatism. The InSight Scleral Lens can incorporate up to +3.00 D of ADD power.

8. Pertinent Patient Information:

Provide details such as:

  • Previous contact lens wear
  • Surgical procedures
  • Visual demands
  • Any factors that could significantly impact the lens design

9. Hydra-PEG (Optional):

Ask during consultation if Hydra-PEG is suitable for the patient.
Hydra-PEG Benefits:

  • Improves wettability by lowering the wetting angle
  • Reduces deposits and fogging

Please call consultation with the above information to discuss further, and we will have the lenses to you in a few short days.

If you don’t have all the information listed above, don’t worry! Our experienced consultants can design a lens based on the details you provide. The more accurate information we receive, the faster we can get the final lens to you.

We are here to support you every step of the way!

Are you looking to offer specialty contact lenses for patients who can’t achieve their best vision with glasses or daily contacts?

Metro Optics’ innovative portfolio enables eye care professionals to source high-quality custom contact lenses, ranging from  mild prescriptions to high-cylinder patients, and even the most hard-to-fit eye conditions.

6 Steps to Success

  1. Network: Spread the word about your services. Reach out to fellow physicians, other specialists, hospitals, and professionals locally and online. Get to know your business neighbors, ask if you can bring literature to their practice, and ask questions about their demographics. Talk to realtors, hair stylists, church members, pickleball league buddies, your child’s friends’ parents—everyone!
  2. Staff Education: Educate your staff with the abundance of free resources on YouTube, the GPLI webinars, and Scleral Lens education Society. Empower staff by getting familiar with ocular conditions, lens modalities, and billing. Schedule lunch and learns with your local reps to learn more about each company and their lens designs. Register your account in the Physician Portal to access Insertion and Removal video tutorials.
  3. Questionnaire: Ask your patients questions about their vision, comfort, dryness, and satisfaction with their current contacts. Often, patients won’t bring up issues unless prompted, assuming their vision is as good as it can be. The doctor can address their answers during the visit.
  4. Patient Education: Offer educational resources for your patients, such as concise one-page handouts that outline the benefits of custom contact lenses. Including information on their options, the proper care systems,  solutions and where to purchase them can enhance patient compliance and over all ocular health.
  5. Leverage Your Labs: Don’t hesitate to ask your labs questions. They are a valuable resource with insights and expertise. Each lab may offer different perspectives on lens modalities, designs and strategy. Let technology do the heavy lifting! Send images to your consultants at info@metro-optics.com to optimize the fitting session.
  6. Current content: Actively updating content on your website and social media profiles helps your ideal patient find your practice when they search online. If your website includes content that addresses their ocular condition, they will be more likely to schedule an appointment with you. Offer resources for them to connect with other people with their condition. For example https://nkcf.org for your Keratoconus patients.

When patients see that you genuinely care about providing the best possible vision rather than just settling for the status quo, they will trust and invest in you because you’ve invested in them. While some patients may be content with their current vision, others will be thrilled that you’ve given them a better option.

Education is powerful. By offering all available options to your patients, you enable them to make informed decisions, enhancing their overall experience and satisfaction.

Bilateral Keratoconus KeraSoft Thin

Patient:24 YO Male College Football Player
Condition: Bilateral Keratoconus

Ocular History:
Undetermined manifest refraction due to high corneal irregularity.

Treatment:
Due to high physical activity and poor GP lens tolerance, lens fit was converted to piggy-back system resulting in BCVA 20/50 OU.

Refit in Kerasoft OU with first fit parameters:
• OD BC 8.40, -4.75 -3.75 X 10, Diameter 15.0, Standard peripheral
• OS BC 8.20, -18.25, Diameter 15.0, Standard peripheral

KeraSoft Diagnostic Fit Set

Outcome:
Dispense visit over-refraction:
• OD +1.25 -1.00 X 45 for 20/20 minus
• OS Plano for 20/20 minus

Remade OD with new lens power
-3.75 -4.50 X 65

Shortly following lens dispense, patient was recruited to a professional practice squad, relocated, and neglected follow-up.

Eight months post-dispense

  • Patient reaches out to report a drop in visual acuity.
  • The patient was instructed to report to the practitioner’s office at their earliest convenience for evaluation.
  • Upon evaluation, Kerasoft lenses exhibit excessive movement along with small over-refraction.
  • This decline in lens performance is due to lenses being used beyond their effective duty cycle.
  • The patient is informed that Kerasoft lenses must be replaced at a recommended 3-month interval.
  • The lenses can perform adequately for up to 6 months, but material degradation will result in poor performance beyond that time.
  • New Kerasoft lenses were ordered in the original parameters and in multi-packs.
  • Original dispense lens performance was restored by the new lenses and the patient was scheduled for routine follow-up.
