PURPOSE: To compare the efficacy of carboxymethylcellulose 0.5% (CMC), hydroxypropyl-guar containing polyethylene glycol 400/propylene glycol (PEG/PG), and hydroxypropyl methylcellulose 0.3% (HPMC) as tear substitutes in patients with dry eye. METHODS: A retrospective evaluation of cases presenting with symptoms of dry eye from July 2014 to June 2015 was done. Patients with Ocular Surface Disease Index (OSDI) scoring >12 were included in the study. Parameters such as age, gender, Schirmer test (ST), and tear film breakup time (TBUT) were recorded on day 0, week 1, and week 4. For analysis, cases were divided into three groups; Group 1 – CMC, Group 2 – PEG/PG, and Group 3 – HPMC. RESULTS: Overall, 120 patients were included in the study. Demographic data and baseline characteristics were comparable among the groups. Group 2 had significant improvement in percentage change in OSDI (weeks 0–1, 0–4, and 1–4, P = 0.00), TBUT (weeks 0–1, P = 0.01; 0–4, P = 0.006; and 1–4, P = 0.007), and in ST (weeks 0–1, P = 0.02; 0–4, P = 0.002; and 1–4, P = 0.008) compared to Group 1 at all follow-ups. Group 3 had improvements similar to Group 2, but it was not at all follow-ups (improvement in percentage change OSDI [weeks 0–1, 0–4, and 1–4, P = 0.00], TBUT [weeks 0–1, P = 0.10; 0–4, P = 0.03; and 1–4, P = 0.04], and in ST [weeks 0–1, P = 0.007; 0–4, P = 0.03; and 1–4, P = 0.12]). No significant difference was found between Groups 2 and 3. CONCLUSIONS: Hydroxypropyl-guar containing PEG/PG and HPMC as tear substitutes are better than CMC. While HPMC was comparable to PEG/PG in subjective improvement, the objective improvement was not consistent.
