CK is safe and very effective
We have performed more than
200 CK procedures, far more than any other centres in
the UK. Here are some of our results, which were presented
by Mr David Allamby, FRCS, FRCOphth at the European
Society for Reractive and Cataract Surgery Conference
in Munich, September 2003.
Figure 1 - Distance
Vision: By 3 months after surgery, 100%
of patients had full binocular vision of 20/20,
whereas prior to surgery, only 51% of patients could
achieve this level of vision. Impressively, 3 out of
4 (73%) patients could see even better with 20/16 vision,
compared to 1 out of 4 pre-CK!

Figure 2 - Reading
Vision: By 3 months after surgery, 100%
of patients could read newspaper sized print, whereas
prior to surgery, only 6% of patients could achieve
this level of vision. 85% of patients could even read
tiny 5 point print, such as you might find at the bottom
of a contract. with a slight reduction in effect, by
6 months, fully 98% of patients could read news and
magazine print, with the other 2% opting for enhancement.
NB: Book print is N10 to N12, news print is often N8

Figure 3 - Distance and Reading
Vision: By 3 months after surgery, 100%
of patients could read newspaper sized print and see
an excellent 20/25 distance vision, whereas
prior to surgery, only 6% of patients could achieve
this level of vision. 85% of patients could
even read tiny 5 point print, AND see 20/20 in the distance,
which 0% of people could do prior to having CK correction.

Figure 4 - Safety of the treatment:
By 3 months after surgery for distance vision,
95% of patients had maintained or even improved their
best potential vision. One in four patients
had actually gained 1 line of vision on the test chart.
No patients lost 2 or more lines of vision.

Figure 5 - Predictabilityof
treatment: By 3 months after surgery
for distance vision, 92% of patients fell within 1 dioptre
of the predicted treatment,significantly above FDA safety
requirements. 68% were within 0.5 dioptres. The trend
line shows a highly predictable result of the FDA treatment
nomogram.
