Abstract: Smart Plugs

I don't care what this study says, I still say DON'T DO IT. I hate SmartPlugs as you all know. The complications may not be widespread but when they happen they are bad, and since good alternatives to this kind of plug exist, there's just no point exposing yourself. Tempting because they're comfy, but... I hate 'em. Too many people have had to have unnecessary surgery on their eyelids dealing with these stupid plugs going places they were never meant to travel.

Clinical efficacy of the SmartPlug™ in the treatment of primary Sjogren's syndrome with keratoconjunctivitis sicca: one-year follow-up study.

To evaluate the efficacy of a thermo-sensitive punctum plug, (SmartPlug™) in Primary Sjogren's Syndrome (pSS) patients with dry eyes, whose symptoms persist despite preservative-free artificial tear treatment. In this study, 22 Primary Sjögren's Syndrome (pSS), as defined by American-European Consensus Group Classification Criteria. All patients being followed up by Ege University Departments of Rheumatology and Ophthalmology. The patients had positive Schirmer test results ( < 5 mm without anesthesia). SmartPlug™ (Medennium, Irvine, California, USA) was inserted into the inferior lacrimal canaliculi of both eyes. Visual acuity measurements, Schirmer I test measurements, lissamine green staining scores, and tear-film breakup times (BUT) were noted before plug insertion and at the 1st, 6th, and 12th months following the procedure. Minimum follow-up period was 6 months for 19 patients and 12 months for 16 patients. Significant improvements were seen in the Schirmer I test scores (before insertion: 1.98 ± 2.67; 1st month: 5.68 ± 6.69; 6th month: 5.35 ± 5.38; 12th month 6.43 ± 5.14 P = 0.006), tear-film BUT in seconds (before insertion: 4.64 ± 3.7; 1st month: 5.80 ± 2.36; 6th month: 7.53 ± 2.92; 12th month 7.50 ± 2.52, P < 0.0001 ), respectively. Thermodynamic punctum plug insertion only in inferior canaliculus is a simple, effective, and comfortable option for treatment of severe aqueous tear deficiency that cannot be controlled using preservative-free tears.
