The paper presents practical and clinical aspects of therapeutic use of SiHy
contact lenses.
Material and
Methods: To evaluate the siHy contact lens as a continuous wear bandage in
selected clinical cases. Prospective, open, non-randomized clinical study was
conducted. Charts of 3398 patients who were fitted with contact lenses for
therapeutic indications (3434 eyes) were analyzed; 2143 women, 1291 men;
aged 27-86. The studies took place from 01.10.2000 to 30.04.2011. Four lens
types manufactured from siHy materials were selected and used for therapeutic
purposes: -lotrafilcon A (Focus Night&Day/ Air Optix Night&Day, Dk:175x10-
11(cm2/s(ml02/(ml x mmHg); CIBA Vision by Novartis Company) – 3349 lenses
were analyzed, study opened 01.10.2000; -comfilcon (Biofinity, Dk:128x10-
11(cm2/s(ml02/(ml x mmHg);CooperVision) – 26 eyes, study opened
20.08.2010; -asmofilcon A (Menicon PremiO, Dk:129x10-11(cm2/s(ml02/(ml
x mmHg); Menicon Co) – 38 lenses, study opened 28.02.2011; -senofilcon
A (Acuvue Oasys Dk:103x10-11(cm2/s(ml02/(ml x mmHg); Johnson&Johnson
Vision Care) 30 eyes, study was performed from 02.02.2006 to 20.06.2006.
Conclusion: SilHy therapeutic contact lenses were assessed positively by us
and our patients and we recommend it as a first choice therapeutic lens in most
cases of today ophthalmological practice.

Objective: Screening in tailors to diagnose ocular problems related with near
work for a long time.
Method: 100 tailors in the age group of 25-50years of age are screened for a
routine eye check-up. Comprehensive eye check-up is performed for all
patients. Out of hundred 36 were female and 64were males. Tailors working
for more than two years were taken in to consideration. Working hours for
each of them were approximately 8 hrs. Patients who showed signs of ocular
fatigability or early presbyopic changes were further evaluated for orthoptics.
Results: Out of 100, twenty-one patients were having myopic astigmatism,
thirty-nine patients presbyopic changes were not in commensuration with age.
Twenty-one patients were normal. Fifteen patients were referred for orthoptic
evaluation. Two patients were having cataract and two were having retinal
problem.
Conclusion: 1) Long term near work gives rise to accommodation insufficiency
and myopic astigmatism. 2) Problems were less in females.

Purpose: 17 civilian aircraft pilots, aged between 45 - 55 years, have been
included on our pilot program. All pilots are from commercial transport: 10
captains and 7 co-pilots. Pilots who participated in our program are facultative
and latent hypermetrop.
Methods: Progressive soft lenses Focus - Ciba, have been ordinated according
to given scheme, by minimum of correction.
Results: Visual equity of all examines is cc 1.0. All examinees achieved
correction of sight in close, keenness of sight Jager II. For civilian aircraft pilot
it›s necessary irreproachable function sense of sight, so use of progressive
contact lenses was proved to be ideal solution for prezbiopy in this profession,
because visual equity was maximum for all distances.
Conclusion: Latitude of sight scope - kinetic perimetry on Goldman instrument
- maximum for all izoptere. Wearing of progressive contact lenses doesn›t have
any influence on adaptation in darkness. (Research was done on Goldman
- Wecker›s instrument). Adaptability is satisfying. Not one of examinees has
given up wearing of prescribed correction lenses.

Purpose: To evaluate the importance of Bi Toric Rigid Gas Permeable Contact
Lens with Mixed Residual Astigmatism cases II.
Method: A 20 years old complaining from reduced vision both eyes at all
distance. The patient was diagnosed to have mixed residual astigmatism. In this
case we need to correct the corneal astigmatism and the lenticular astigmatism
in same time. His uncorrected visual acuity was 20/400+ at distance (right eye)
and 20/400 at distance (left eye). Best corrected visual acuity was 20/70 (right
eye) and 20/70 (left eye) with manifest refraction ¯7.00/¯5.50 x 176 (right eye)
and ¯6.00/¯6.00 x 147 (left eye) III.
Results: The patient was tested with trial Bitoric R.G.P. the vision improve up to
20/30+ (right eye), 20/25+ (left eye).
Conclusion: The BI TORIC Rigid Gas Permeable contact lenses still is the best
solution to improve the vision for Mixed Residual Astigmatism cases.

The Management of Post Traumatic Irregular Corneal Astigmatism,
Aphaki and Iridodialysis by Contact Lens

Purpose: To evaluate the piggyback technique with post traumatic irregular
corneal astigmatism, aphaki and iridodialysis by contact lens II.
Method: 25 years old complaining of reduced vision (left eye). The patient eye
examination shows old trauma leaded to rupture globe His uncorrected visual
acuity was 20/20 at distance and near (right eye) and C.F 1 m at distance
(left eye). Best corrected visual acuity was C.F 3 m, with manifest refraction
+14.00/5.50 x 160 (left eye).The patient was diagnosed WITH left eye rupture
globe status of aphakia and irregular corneal astigmatism III.
Results: The patient was tested with piggy back technique, which means I will
fit the patient with soft color contact lens, and then I will fit him with aphakic
rigid gas permeable lens over the soft one. -The vision improve to 20/40(left
eye) corrected with contact lens (with piggyback technique).
Conclusion: Traumatic Aphakia and Iridodialysis can cause both drop in visual
acuity and hetrochemia, we usually use the piggy bank technique in
keratoconus patient, but sometimes we need to be ready for any recent cases
‹such as the above case›.
