The Future of Dry Eye Diagnosis & Cataract Treatment

14 Jul 2025

When it comes to cataract surgery, dry eye disease (DED) isn’t just a side issue; it’s a major consideration that can (and does) significantly impact the treatment of cataracts. Anywhere between 50% to 70% of those with cataracts also have dry eye disease, or another type of OSD, which is still regularly overlooked or misdiagnosed.  Despite this, diagnosis and treatment still vary dramatically from practice to practice. Some rely on slit lamps and patient-reported symptoms. Others use more sophisticated tools. And while the intention is the same (to make sure the eye is in optimal condition before surgery), the results can be wildly inconsistent. At Mainline, we believe that standardising dry eye diagnosis matters, especially before cataract surgery.

Why is proper dry eye diagnosis essential?

Whether you’re running a high-street optometry practice or working in a surgical centre, assessing the ocular surface before cataract surgery is crucial. We know that dry eye disease, especially if it’s undiagnosed or untreated, can interfere with pre-operative measurements, affect refractive outcomes, and delay recovery. Even worse, the surgery itself (by disrupting corneal nerves or triggering inflammation) can cause or worsen dry eye symptoms. Checking for DED early is extremely important, as early treatment prevents long-term issues and delivers significantly better patient outcomes.  But here’s the problem: dry eye can be caused by a whole manner of things:
  • Environmental factors (air conditioning, wind, smoke, strong sunlight, air pollution, etc.)
  • Systemic medications
  • Allergies
  • Meibomian gland dysfunction 
And yet many patients are still lumped into one generic “dry eye” category. Without the right tools, it’s hard to know what you’re really dealing with. That’s where better diagnostics come into their own.

The OCULUS Keratograph 5M – the gold standard in dry eye diagnosis

There’s no shortage of dry eye assessment tools on the market. But not all of them are built to give a clear, consistent diagnosis, especially when you’re looking to follow best-practice protocols like TFOS DEWS II and III. If you’re serious about delivering consistent, compliant dry eye assessments, the OCULUS Keratograph 5M is the tool you need; a true industry gold standard.  Built specifically with dry eye diagnosis in mind, the K5M allows clinicians to go beyond guesswork or patient-reported symptoms. It identifies key biomarkers and provides a detailed visual report covering:
  • Tear film quality and stability
  • Meibomian gland imaging
  • Tear meniscus height
  • Non-invasive tear break-up time (NIBUT)
  • Redness grading and more
Unlike subjective methods like the slit lamp, the Keratograph 5M gives you an objective, repeatable measure that helps you track treatment progress and make more informed clinical decisions. Whether you’re in a surgical centre or a specialist dry eye clinic, this is your top-tier solution for accurate diagnosis, better outcomes, and total clinical confidence.

The TOMEY MR-6000 – a multifunctional diagnostics tool for modern optometry

If you’re looking for flexibility and functionality in one unit, the TOMEY MR-6000 delivers. Ideal for busy practices that want to combine dry eye assessments with wider refractive diagnostics, the MR-6000 is a true all-rounder. It offers:
  • Refraction
  • Tonometry (IOP)
  • Corneal topography
  • Blink analysis
  • Tear film measurement
  • Pupil diameter and corneal thickness
This makes it a powerful tool for community optometrists who are involved in cataract screening and ongoing patient management, especially those working in referral pathways with private hospitals. Its dry eye diagnostic features include blink rate tracking and tear film stability, helping you detect signs of ocular surface disease early, even if patients aren’t yet symptomatic.

The OCULUS ImageCam® 3 – entry-level imaging that provides fantastic clinical value

For practices just beginning their dry eye journey, or those wanting to enhance their existing slit lamp capabilities,  the OCULUS ImageCam® 3 is a smart first step. This device attaches to any slit lamp to provide high-quality imaging for:
  • Meibomian gland evaluation
  • Ocular surface documentation
  • Patient education and case tracking
It doesn’t offer the full diagnostic suite of the K5M, or the multi-functionality of the MR-6000, but it’s a great way to bring more consistency and documentation into your dry eye assessments. It’s particularly valuable for patient communication, as it helps you show, not just tell, what’s happening with their ocular surface. Learn more about the OCULUS ImageCam® 3
