Intralamellar dissection techniques in lamellar keratoplasty.

摘要: PURPOSE To evaluate and compare the efficacy of four adjunctive agents to facilitate recipient bed intralamellar dissection in cases lamellar keratoplasty. METHODS Forty eyes with partial-thickness corneal opacities were recruited for this prospective, randomized clinical trial. The divided into groups per injection (i.e., air [group I], 2% hydroxypropyl methylcellulose [HPMC] II], balanced saline solution [BSS] III], no adjunct IV] used dissection). intraoperative parameters evaluated initial preparation time, total time. At each follow-up, visual acuity, refractive status, keratometry, endothelial cell counts also analyzed. RESULTS Initial time significantly decreased use an (p < 0.05) found be least BSS. No difference these frames was noted between group I II. Corneal haze incomplete insufflation seen I, difficulty HPMC its spread mean spherical equivalent, astigmatism, counts, acuity did not show any significant group. CONCLUSION Hydrodelamination BSS is easy perform should undertaken routinely dissection.
