For the surgical procedure there was no induced astigmatism and PCO was only observed in four eyes out of 258 during final
follow-up, 5–18 months post-op. The results revealed that 96% of patients achieved binocular uncorrected distance visual acuity
(UCVA) of 20/32 or better [Figure 1(a)] and 97% of patients could read J2 or better without correction, including 76% of patients
achieving J1 or better [Figure 1(b)]. Intermediate vision at 50 cm (computer reading distance) was also excellent with 92%
of patients reading J3 or better without correction including 28% of patients reading J1 or better [Figure 1(c)].

The questionnaire was completed by 94 of the 129 patients and it was revealed that overall satisfaction was high with 96.8%
of the respondents stating they would use the implant again and 92% were very satisfied or satisfied with the procedure (Figure
2). In addition to these results a high proportion of the respondents to the questionnaire were able to function without glasses
for far, near and intermediate distances. Halos and glare were also less of a problem with almost half reporting that they
did not experience either after surgery (Figure 3).
Figure 3: Overall patient satisfaction results.
"Our study included only patients with cataracts, the majority of whom were satisfied. Overall, my experience in clear lens
extraction for refractive purposes (essentially for hypermetropic patients older than 55) seems to give much better results
in the quality of vision and the level of satisfaction," Dr Zaluski concluded. "One important point to note, however, is that
this lens needs a very safe and gentle insertion with an appropriate injector because of the quick unfolding that is characteristic
of any silicon lens."
Dr Serge Zaluski has a private practice with an interest in cataract and refractive surgery. He works in the VISIS ophthalmological centre
in Perpignan, South of France, with colleagues involved in glaucoma, cornea and retina practice.
