PURPOSE. As patient populations age, clinicians treat more severe dry eyes (DE). Relief from pain and symptoms DE induces has no cure. Moisture chamber spectacles (MCS) are prosthetic devices coupled to eyeglasses that slow evaporation of tears from the ocular surface. A determination about the level of symptom relief by MCS in DE patients is conducted. Clearly effective DE treatment is needed in optometric care. METHOD. Forty-one surveys were returned, 22 (19 females, 3 males) from respondents fitted with MCS. The average age of survey sample (± S.D.) was 59 ± 16 years and had DE for 8.2 ± 5.9 years. Seven wore single vision and thirteen multifocal lenses (two not reporting).
RESULTS. Fifty percent of respondents reported satisfaction to complete satisfaction for all questions. Respondents wearing MCS reported significantly higher ratings than those who discontinued. There was a positive correlation between the hours/day that respondents wore MCS and comfort (Spearman rank, r=.5, P=0.043, N=17). Patients received their MCS 3.4 ± 2.7 years ago. It required three or four visits to be fit with MCS (17 of 21 answering). Five of 21 report received at least partial insurance coverage. Eight of 22 no longer wear MCS. Five of these provided comments on reasons for discontinuation: hindered peripheral vision (1), claustrophobic sensation (1), fogging (2), and unattractive (1). Patients reported they wore (before discontinuing if they no longer wore MCS) MCS an average of 9.6 ± 5.9 hours per day (17 reported including five who discontinued use). There was positive correlation between the hours/day that respondents wore MCS and assessment of comfort (Spearman rank, r=.5, P=0.043, N=17).
CONCLUSIONS. DE patients obtain relief from symptoms according to the number of hours MCS are worn. MCS offer increased comfort to patients regardless of the primary mechanism for tear problems.
