The primay aim of this study was to comparre the incidnce of contact
lens related complications in neophytes wearing conventional and disposable
soft contact lenses.
A total of 40 subjects was included in the study and fitted with FDA
Group IV soft contact lenses. The subjects were divided into 2 groups.
Groups (A) included 20 subjects who were fitted with conventional soft
contact lenses (methafilcon A-55% DEC = 18). Group (B) inch) firsd 20 subjects
fitted with weekly disposable soft contact lenses (Ocufilcon D-55%
DK = 19.7). The subjects were asked to wear the lenses on daily - basis
and dispose them after a month, report to the clinic to receive a new pair.
In-group (A), 4 cases (20%) developed moderate corneal vascularization
by the end of first year of lens wear. In group (B) mild timbal vascularization
developed in 6 cases (30%). In-group (A), 8 cases (4O%) developed
tarsal conjunctival congestion by the end of first year of follow-up.
In group (B) mild (grade 2) tarsal conjunctival congestion occured in (20%)
of cases. Contact lens papillay conjunctivitis developed in only 2 cases
(10%) in-group (A). The overall incidence of corneal infiltate in both groups
was (15%). In-goup (A) corneal infiltrates developed in 4 cases (20%). Ingroup
(B) the incidence of infiltrates was less (10%) - 2 cases only. Contact
lens detectd after the ninth month of lens wear in 4 cases (20%) ingroup
(A) only. Corneal staining was detected in one subject (5%) in-group
(B). |
