Contact lens examination 

A contact lens examination is a specialized examination conducted by an eye care professional to determine the suitability of contact lenses for an individual and to ensure proper fit, comfort, and vision correction. What typically occurs during a contact lens examination:

  1. Evaluation of Eye Health: Using specialized instruments such as a biomicroscope (slit lamp), the eye care professional will examine the health of the patient's eyes, including the cornea, conjunctiva, and eyelids. This evaluation helps identify any conditions or issues that may affect contact lens wear.

  2. Corneal Measurements: The curvature and size of the cornea are critical factors in determining the appropriate fit of contact lenses. Various techniques, such as keratometry and corneal topography, may be used to measure these parameters.

  3. Contact Lens Selection: Based on the patient's prescription, eye health, and corneal measurements, the optometrist will recommend a type of contact lens that suits the individual's needs. This may include soft contact lenses, rigid gas permeable (RGP) lenses, toric lenses for astigmatism correction, multifocal lenses for presbyopia correction, or specialty lenses for specific eye conditions.

  4. Trial Lenses: If deemed appropriate, the patient may be provided with trial contact lenses to evaluate their comfort, fit, and vision correction. During this phase, the eye care professional will assess the position of the lenses on the eye, movement, centration, and overall comfort.

  5. Final Prescription and Instructions: Based on the trial lens evaluation and any adjustments made, the eye care professional will finalize the contact lens prescription and provide instructions on proper lens insertion, removal, cleaning, and maintenance.

  6. Follow-Up Visits: Follow-up visits may be scheduled to monitor the patient's adaptation to contact lens wear, assess the fit and comfort of the lenses, and make any necessary adjustments.
