What Is I&R (Insertion & Removal) Training?

How Does Hands-On Training Reduce the Risk of Corneal Abrasions?

The primary risk for new wearers is mechanical trauma to the eye surface caused by "poking" or "pinching" too hard. I&R training teaches the "two-finger" technique, where the eyelids are held firmly open while the other hand gently places the lens on the white of the eye. By learning to slide the lens onto the cornea rather than "dropping" it, the patient avoids the risk of a corneal abrasion. Clinical data suggests that patients who receive formal I&R training are 60 percent less likely to visit an emergency room for an "eye scratch" during their first month of wear.

What are the Primary Success Data Trends for New Wearer Retention?

Retention data shows that the quality of the I&R training is the leading predictor of whether a patient will remain a contact lens wearer long-term. Nearly 25 percent of new wearers drop out within the first ninety days, and the most common reason cited is "difficulty with handling." Patients who feel confident after their training session are 40 percent more likely to continue wearing lenses for at least five years. This highlights why many modern clinics now allot a full hour for this training to ensure the patient feels calm and capable before they leave the office.

Why is Hand Hygiene the First Lesson in Every I&R Session?

Infection prevention starts before the lens even touches the eye. The first step of every I&R training is a thorough lesson in handwashing using "non-perfumed" and "non-oily" soap. This prevents the transfer of oils, perfumes, and pathogens from the fingers to the lens material. Training also emphasizes the importance of drying hands with a lint-free towel to ensure that no fibers are trapped behind the lens, which is a common cause of "unexplained" irritation for new users.

What are the Most Common Challenges Taught During Removal Training?

Removal is often more difficult for new wearers than insertion, as the "fear reflex" can cause the eye to roll up or blink. Technicians teach the "pinch" method, where the patient gently slides the lens down into the lower part of the eye before squeezing the material to break the suction. If a patient struggles, the trainer may introduce tools like a "plunger" for rigid lenses or specialized mirrors. Ensuring the patient can remove their lenses in the dark or without a mirror is an essential part of "emergency" handling skills.

How Do Clinicians Handle Patients with "Severe Blink Reflex"?

A strong blink reflex is the biggest barrier to successful contact lens wear. During training, clinicians use "desensitization" techniques, such as having the patient touch their eyelids and practice holding their lashes without blinking. For some, this process may take several sessions before they are comfortable enough to try the actual lens. Being patient and using a supportive, non-pressured environment allows even the most "squeamish" patients to eventually master the skill of I&R.
