PURPOSE: To critically appraise the evidence on the efficacy and recanalization rates of permanent punctal occlusion via thermal or surgical means in managing dry eye disease (DED).
METHODS: In PubMed, Scopus, and Cochrane databases, two authors systematically reviewed the literature for prospective studies on punctal cautery or surgical occlusion (excluding punctal plugs) for DED. The studied outcomes were changes in tear volume, tear film stability, punctal recanalization rates, and patient symptomatology.
RESULTS: Nine studies (all single-arm) had 150 subjects (96 females). Five studies were on thermal punctal cauterization, and four used surgical occlusion techniques. One hundred eighty puncta were operated for eyes not responding to maximal lubricants or recurrent plug extrusion. DED etiologies were Sjogren's syndrome (78), cicatricial ADDE (27), graft-versus-host disease (12), and non-SS DED (50). Follow-up ranged from 3 to 24 months. At the final follow-up, improvements in Schirmer I and TBUT were 2.5 mm and 0.8s with thermal and 2.1 mm and 0.6s with surgical methods, respectively (P = 0.17 for Schirmer, P = 0.18 for TBUT). Punctal recanalization rates varied between thermal (0-38.7 %) and surgical (5-9%) techniques (p = 0.22). Different cautery devices show different recanalization rates; disposable thermal cautery tips directly inserted into the punctum had lesser recanalization than radiofrequency monopolar cautery. Most patients reported subjective improvement following the procedure, but no quantification measure was given in the studies. None of the published studies had a comparison group for performing a meta-analysis.
CONCLUSION: Based on non-comparative studies, thermal or surgical punctal occlusion improves tear volume in DED with similar recanalization rates; however, randomized controlled trials are needed to ascertain the real effects of punctal cautery on DED.
