| Summary: |
Aim: The aim of the study
was to determine therapeutic use of the soft
silicone-hydrogel senofilcon A contact lenses of Dk/t
147, BC 8.4 and diameter of 14.0 with surface
modification with Hydraclear® Plus system in patients
with primary and secondary tear film disorders due to
the various corneal conditions.
Material and Methods: 40 patients (40 eyes), 32 women
and 8 men, whose corneal condition qualified for
therapeutic lens application. Those were patients with
following ocular conditions: bullous keratopathy (4 eyes),
burns (3 eyes), corneal erosions (6 eyes), neurogennic
keratitis (3 eyes), descemetocele (4 eyes), corneal
ulcers (4 eyes) keratitis (3 eyes), uveitis (2 eyes),
acne rosacea (2 eyes), Graves-Basedov ophthalmopathy (2
eyes), Sjögren’s syndrome (7 eyes).
In all patients following examinations were performed at
baseline: distance and near BCVA, complete
ophthalmologic examination in the slit-lamp, intraocular
pressure, according to the possibilities – using Goldman
applanation or palpation method, evaluation using
TEARSCOPE-PLUS®, NBUT, Schirmers I test after
conjunctival anesthesia, color photo of the anterior
segment with white light, cobalt blue filter and yellow
filter, fluorescein / lysamine green staining, LIPCOF
folds, tear meniscus, tear prism
After contact lens application in all patients the same
examinations were performed as during the baseline
evaluation plus subjective wearing comfort evaluation by
the patient and subjective patient’s evaluation before
lens application, during lens wearing and after lens
removal. The objective evaluation was performed using
following scales: limbal hyperaemia, corneal staining,
conjunctival staining, stromal edema. Tolerability and
comfort was evaluated based on the form created by
authors, which was filled by patients during follow-up
visits. Follow-up time was 6 months.
Results and Conclusions: In all fitted patients good or
very good and satisfactory tolerability with special
focus on wearing comfort was observed. As it is well
known each type of contact lens deteriorates pre-lens
film and tear film stability. It is also well
established in cases of hydrogel lenses one may not be
able to see any pre-lens tear film at all or the tear
film is extremely unstable. We have observed
satisfactory parameters of the pre-contact lens tear
film. On the basis of our study we can recommend
senofilcon A contact lens as a very good choice for all
types of patients both for therapeutic and optic
indications. |
