Is the Use of Empirically Designed Custom Soft Contact Lenses a Good Option for Challenging Patients?
60
e.g. coma, due to the thickness of the hioxifilcon D con-
tact lens material [13,17].
5. Conclusions
The results of this study suggest that empirically de-
signed custom fit soft contact lenses:
• Fit most refractive parameter combinations and cor-
neal profiles;
• Allow fast and easy correction of high astigmatic re-
fractive errors;
• Provide good patient comfort;
• Reduce chair-time;
• Increase the first pair fit success rate.
The virtually unlimited range of parameters with these
lenses assures availability of the optimal lens for each
patient’s condition, and may have a positive impact on
patient compliance and loyalty. A rigorous cleaning and
disinfecting regimen in combination with planned lens
replacement is necessary to maintain optical quality as
well as hydrophilicity, and to decrease the accumulation
of long term deposits on the contact lens material. It ap-
pears that a 3-month replacement cycle is appropriate for
these lathe-cut manufactured custom soft lenses.
Additional research with a larger sample of normal as
well as compromised corneas, different lens types and
materials is planned for future studies.
