In\n          this retrospective study, we compared the effectiveness and the recurrence rate for both\n          methods.<\/jats:p>\n                  <jats:p>Patients\/Material and Methods We conducted a retrospective study of patients with\n          idiopathic BK who had been treated with EDTA-chelation or PTK and who had no other\n          relevant corneal disease. Of 81 patients, 34 were treated with EDTA chelation and 47 with\n          PTK. Demographic data, comorbidities, pre- and postoperative visual acuity, preoperative\n          severity of the disease and technical surgical parameters were recorded. The results were\n          compared descriptively. A telephone survey was conducted to investigate the subjective\n          outcome after surgery and the development of recurrences.<\/jats:p>\n                  <jats:p>Results Regardless of the preoperative severity of BK, treatment intensity and\n          comorbidities, this study confirmed an equal improvement in visual acuity with both EDTA\n          chelation and PTK. The telephone survey showed that the recurrence rate after PTK was\n          significantly lower than after EDTA-chelation (chi-square\u2009=\u20094.74; p\u2009=\u20090.03, n\u2009=\u200925).\n          However, the postoperative symptomatic relief was similar in both groups.<\/jats:p>\n                  <jats:p>Conclusion EDTA chelation and PTK as treatment of BK provide equivalent\n          improvement in visual acuity and postoperative symptomatic relief. A lower recurrence rate\n          may be expected with PTK. Further prospective studies would be necessary to confirm our\n          results.<\/jats:p>","DOI":"10.1055\/a-2760-3432","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T23:59:39Z","timestamp":1770940779000},"page":"697-703","source":"Crossref","is-referenced-by-count":0,"title":["Dissolve or Evaporate: an Update to Treatment Modalities in\n          Band-like Keratopathy"],"prefix":"10.1055","volume":"243","author":[{"given":"Tonio Felix","family":"Schaffert","sequence":"additional","affiliation":[{"name":"Augenklinik, Universit\u00e4tsklinikum Freiburg, Deutschland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"B\u00f6hringer","sequence":"additional","affiliation":[{"name":"Augenklinik, Universit\u00e4tsklinikum Freiburg, Deutschland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Reinhard","sequence":"additional","affiliation":[{"name":"Augenklinik, Universit\u00e4tsklinikum Freiburg, Deutschland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip Christian","family":"Maier","sequence":"additional","affiliation":[{"name":"Augenklinik, Universit\u00e4tsklinikum Freiburg, Deutschland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2026,2,12]]},"reference":[{"key":"ref1","first-page":"114","volume-title":"Diseases of the eye","author":"J Dixon","year":"1848"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"222","DOI":"10.1016\/s0002-9394(34)92585-x","article-title":"Band Keratitis","volume":"17","author":"R J Sisson","year":"1934","journal-title":"Am J Ophthalmol"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1177\/112067219200200106","article-title":"Treatment of calcific band keratopathy by Nd:YAG laser","volume":"2","author":"S Baltatzis","year":"1992","journal-title":"Eur J Ophthalmol"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"1009","DOI":"10.1097\/OPX.0000000000001134","article-title":"Effect of Scattering and Aberrations on Visual Acuity for Band Keratopathy","volume":"94","author":"K Kamiya","year":"2017","journal-title":"Optom Vis Sci"},{"key":"ref5","first-page":"550","article-title":"Treatment of band keratopathy","volume":"80","author":"T O Wood","year":"1975","journal-title":"Am J Ophthalmol"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"1895","DOI":"10.2147\/OPTH.S177636","article-title":"Removal of calcific band keratopathy without ethylenediaminetetraacetic acid (EDTA) in\n          eyes with limited visual potential","volume":"12","author":"C R Bee","year":"2018","journal-title":"Clin Ophthalmol"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"111","DOI":"10.1097\/00003226-200303000-00005","article-title":"Indications and outcome of optical partial thickness lamellar keratoplasty","volume":"22","author":"J S Saini","year":"2003","journal-title":"Cornea"},{"issue":"11","key":"ref8","first-page":"579","article-title":"La k\u00e9ratopathie en bandelette.
