Purpose: To asses the visual performance of patients following cataract
extraction with implantation of three types of IOL and to compare the perception
and visual fatigue during typical office work depending on IOL type.
Methods: 39 patients were enrolled in this prospective study and divided to 3
groups of equal quantity: I- with monofocal AcrySof SA60AT, II- monofocal
aspheric AcrySof SA60WF, III- multifocal AcrySof ReSTOR SN6AD1.The
follow up tests, consisted of BCVA for distance and near, contrast sensitivity,
computer and printed text visual tasks were performed in the intervals of one,
three, six and twelve months in special prepared laboratory-room.
Results: Of tests were statistic analyzed. After proper time of visual fatigue
patients filled in questionnaire concerning their visual discomfort symptoms
and opinions of light preferences.
Conclusions: BCVA for distance is comparable in all groups and BCVA for near
differs in groups 1vs 3. Contrast sensitivity vary in all groups at marginal
significance level. Visual fatigue and discomfort symptoms during office work
were comparable and individuals accomplished computer and printed text
visual tasks at comparable time with comparable numbers of mistakes. No
changes in light intensity during office work due to type of IOL were needed.

Problems: Until now multifocal lenses, either diffractive so refractive are based
on rotational symetry with concentric rings. Furthermore these effects will
added by corneal aberration and astigmatism. The Lentis Mplus IOL with
concept of rotational asymetry features a completely approach in multifocal
lens technology. In this study shall presented the influence of pupil diameter,
decentration and corneal astigmatism on the aberrometry and visual quality.
Methods: At 87 patients were implanted a LENTIS Mplus and after the
implantation were measured the far and near visual aquity and the aberration
at different pupil diameter after mydriasis was applyed. The measurement of
the aberrometry was occurring with the zywave (B&L) and with the wavescan
(AMO. Furthermore the measurements were also occur at 7 cases after a laser
touch up for the residual corneal astigmatism and refraction.
Results: Both aberration, near visual aquity and subjective patient satisfaction
are dependent of the pupil diameter. Also an influence has the postoperative
capsular shrinkings.
Conclusion: At the preoperative patient selection are introduce the pupil
diameter, corneal astigmatism and the option of a postoperative corneal laser
touch up.

Limited Aspects in LASICAT Surgery

Purpose: After the combination of LASIK and lens surgery (“Bioptics”) has
extended the spektrum of refraktive treatments , it was logical to examine
the possibilities of the femtosecond laser. In addition to the preparation of
the lasikflap with the femtosecond laser it is possible to do corneal incisions
in cataract surgery, capsulorhexis and the crushing of the lens nucleus with
the same laser. The concept LASICAT (“lasers in cataract surgery”) has been
presented 2004 by the author.
Every method has advantages and disadvantages. After the technical
realization of the LASICAT-concept as “femto-phaco” or “femto-cataract” it is
necessary to point out limits and contraindications of this method. methods
Separate working steps as well as the advantages of applying the femtosecond
laser will be presented. On individual examples limited organic aspects will be
illuminated.
Results: To the limiting factors belong for example corneal scars, subluxation
lentis, hard nucleus, narrow orbita and increased bulbus reducibility.
Conclusion: Beside the advantages of applying the femtosecond laser in
cataract surgery (“LASICAT”, “femto phaco”) there are organic limiting factors.
These should be taken into account for planning the surgery.

Purpose: The purpose of this paper is to determine the efficiency of surgical
correction of astigmatism after implantation of Acrysof Toric intraocular lenses
at patients with cataract and corneal astigmatism.
Methods: Currently, the most often applied corneal astigmatism removal
methods cover: laser surgery or toric intraocular lenses implantation. In
research we have applied the Acrysof Toric IOL - one-part hydrophobic acrylic
lenses. The retrospective research covered 48 eyeballs in 42 cataract and
corneal astigmatism patients.
Results: In test group 76,93% post-surgical patients (facoemulsification and
toric lens implantation) gained the best uncorrected visual acuity ranged 0,9-
1,0; 15,38% patients gained the visual acuity ranged 0,7-0,8 and in 7,69%
patients the acuity was 0,4-0,6. The lens rotation was estimated three months
after the surgery and the 3, 24±3,41 degree axial displacement was observed,
however, which was clinically unimportant. Based on the after-surgical results`
analysis the corneal astigmatism was lowered by 84,2%. One of the patients
was diagnosed with opacity of posterior lenticular capsule.
Conclusions: Based on the carried out observation, we may notice clinically
and statistically important vision acuity improvement among the corneal
astigmatism patients. The patient`s satisfaction is conditioned by proper presurgery
qualification.

Objective: We implanted bitoric MICS IOL after CO-MICS surgery in a 69-old
man with hyperopia, cataract and keratokonus in both eyes.
Methods: Monofocal bitoric IOL with cylindrical power of 4 and 5 diopters were
implanted through a 1.6 mm incision after phacoemulsification. Postop
aberrometry, videokeratography and subjective outcome were examined.
Results: The preliminary analysis showed an improved optical image quality
and refraction after implantation of IOL. The patient reported that he had never
seen better in his live before even with glasses or contact lenses.
Conclusion: Keratokonus patients with cataract can be treated very well with
bitoric IOL after CO-MICS.
