In lamellar keratoplasty, the healthy and clear portions of the recipient\u2019s own cornea are preserved, significantly decreasing surgical trauma and the chance developing host-versus-graft disease. In anterior lamellar keratoplasty, the inner layers of the cornea (Descemet\u2019s membrane and corneal endothelium) are preserved. This technique significantly extends the life span of the transplanted cornea (to up to 49 years).<\/p>\n<p>This procedure is very precise, limited to removing a tissue fragment of up to 300-500 microns in thickness. This very delicate method requires high-tech equipment and special surgical skills. Trephination devices with micrometre scales or femtosecond laser systems are needed to perform the surgery.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section><section class=\"l-section wpb_row height_custom\"><div class=\"l-section-h i-cf\"><div class=\"g-cols vc_row via_flex valign_top type_default stacking_default\"><div class=\"vc_col-sm-12 wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"w-iconbox us_custom_70facfb4 iconpos_left style_default color_secondary align_left no_text\"><div class=\"w-iconbox-icon\" style=\"font-size:3rem;\"><i class=\"fad fa-eye\"><\/i><\/div><div class=\"w-iconbox-meta\"><h2 class=\"w-iconbox-title\" style=\"font-size:1.2rem;\">When is anterior lamellar keratoplasty indicated?<\/h2><\/div><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><p>Cornea diseases is the fourth-most common cause of blindness in the world population.
