marking system which creates corneal marks for proper toric intraocular lens
(IOL) placement to improve results of premium IOL surgery and limbal relaxing
incision surgery. </span> </p> <p> </p> <p class="MsoNormal" style="margin-bottom:.0001pt;text-align:justify;line-height:200%;"> <b> <span style="font-family:’Times New Roman’, serif;">Material
and Method: </span> </b> <span style="font-family:’Times New Roman’, serif;">Patients
were randomly allocated into two groups for preoperative corneal marking in the
sitting position. A conventional pendulum marker and the new marking system
were compared for vertical misalignment and rotational misalignment. A
high-resolution anterior segment camera was used to document the corneal
markings, and rotational deviation and vertical misalignment were evaluated. </span> </p> <p> </p> <p class="MsoNormal" style="margin-bottom:.0001pt;text-align:justify;line-height:200%;"> <b> <span style="font-family:’Times New Roman’, serif;">Results: </span> </b> <span style="font-family:’Times New Roman’, serif;">Each group
consisted of 40 eyes and all marking points were clearly identified. The mean
vertical misalignment in the pendulum marking group and in the new marking
system group was 0,71± 0,62 mm and 0,24 ± 0,12 mm, respectively.
There was a statistically significant difference in vertical misalignment
between the two groups (p < 0,05). The mean rotational deviation in the
pendulum marking group and the new marking system group was 1,9 ± 2,4 degrees
and 0,8 ± 1,3 degrees respectively, showing a statistically significant
difference (p < 0,05). </span> </p> <p> </p> <p class="MsoNormal" style="margin-bottom:.0001pt;line-height:200%;"> </p> <p class="MsoNormal" style="margin-bottom:.0001pt;line-height:200%;"> <b> <span style="font-family:’Times New Roman’, serif;">Conclusion: </span> </b> <span style="font-family:’Times New Roman’, serif;">While the conventional pendulum marker showed a
certain amount of deviation and vertical misalignment, the new marking system
marked the desired axis and minimized some possible measurement errors. During
use of the new system, the entire cornea and conjunctiva were visible and the
procedure was controlled perfectly. </span> </p> <p> </p> <p> </p>}, number={4}, publisher={MEDİTAGEM Ltd. Şti.}
