The RGP lens wear test was equivalent or superior to the hydrogel control performance in all categories. To evaluate the standards of contact lens practice in Portugal, with particular attention paid to the characteristics of first fits and refits regarding aspects such as symptoms of dryness, overnight wear, silicone hydrogel and multifocal prescriptions, and care systems.

Rigid gas-permeable (RGP) contact lens fitting is often regarded as more complex than soft lens fitting, but in reality, the number of decisions practitioners must make is essentially the same when judging the fit of either lens. In addition, modern RGP lens designs can fit a wide range of the normal ametropic population, so practitioners need only specify the back optic zone radius (BOZR), total diameter (TD) and back vertex power (BVP) from a particular lens design for the manufacturer to produce the lens.

The final decision on the RGP lenses dispensed relied upon the clinical evaluation (slit lamp examination, fluorescein pattern, lens centration, and visual acuity). Clinical evaluation remains mandatory in determining the appropriate RGP lens.

Eye & Contact Lens: Science & Clinical Practice: July 2003 - Volume 29. .Three patients discontinued lens wear. In one patient, the lens was not stable, and the other two experienced discomfort with their lenses.

Eye & Contact Lens: Science & Clinical Practice: July 2003 - Volume 29 - Issue 3 - p 168-172. Forty eyes of 24 patients were fitted with RGP contact lenses during the study period. Sixteen were male patients and eight were female patients. The age of the patients ranged from 13 to 59 years, with a mean of 3. years. Spherical rigid gas-permeable lenses are a good option for patients even with advanced PMCD.

RGP Fitting Assessment . Hallmarks of an optimal RGP lens fit include : 1. Patient comfort 2. Good lens centration 3. Lens–cornea alignment. RGP contact lenses in presbyopia For the presbyopic RGP wearer who wishes to continue with lenses there are a number. Alternating squinters are ideal, as they are well practiced in suppression of the non-fixating eye., this method enjoys higher success rates (50% and 86% ) than multifocal contact lens fitting, but it doesn't suit everyone !

Advise all contact lens patients to bring their contact lens cases and glasses with them . Instill fluorescein if patient is an RGP lens wearer. The contact lens Rx must be released after the contact lens fitting has been completed and the patient is responding satisfactorily to the lenses.

Advise all contact lens patients to bring their contact lens cases and glasses with them to progress examinations since you will be instilling fluorescein as part of the routine evaluation procedure on all patients regardless of lens type worn at each and every visit. Patients will be informed that modification of rigid lenses not obtained/purchased from our clinic will be done at their own risk due to possible breakage. Note bearing relationship, lens position and movement.

Rigid contact lenses are prone to trap debris beneath the lens and are clearly contraindicated in dirty and dusty environments. Also, dirty and dusty sporting environments are typically associated with intense physical activity and a greater risk of dislodging the lens, which are further factors contraindicating the use of rigid lenses. Wearers of RGP lenses experience less contact lens related complications than wearers of soft lenses and have a lower incidence of serious complications such as microbial keratitis (Morgan et a. 2005).
