“…They also make contact lens correction intolerable, because of the poor fit between the lens and the cornea (Rabinowitz, 1998;Smiddy et al, 1988). Following the advanced stage, keratoconus may further develop into the complication stage with spontaneous Descemet's membrane (DM) tears causing highly acute stromal edema (Sharma et al, 2011), and even the occasional occurrence of perforation (Yeh and Smith, 2008). Although most keratoconus with acute hydrops can resolve automatically, a residual scar will persist (Tuft et al, 1994;Rabinowitz, 1998).…”

Abstract:Objective: To compare postoperative outcomes of full-bed deep anterior lamellar keratoplasty (DALK) with penetrating keratoplasty (PK) in treating keratoconus. Methods: Seventy-five eyes of 64 patients who received full-bed DALK and 52 eyes of 51 patients who received PK between June 2000 and August 2010 were included in this retrospective study. Full-bed DALK was performed using Yao's hooking-detaching technique. PK was performed using a standard technique. Intraoperative and postoperative complications, visual acuity, rejection, graft survival, endothelial cell density, corneal sensation recovery, and re-innervation were compared between the two groups. Results: A best correct visual acuity of 0.5 or better was achieved in 90.7% of eyes after full-bed DALK and in 92.3% of eyes after PK (P=0.75). By the fifth postoperative year, graft endothelial cell loss reached 34.6% in the PK group vs. 13.9% in the full-bed DALK group (P<0.001). There were no statistical differences in corneal sensitivity recovery or corneal re-innervation between the groups (P>0.05). Intraoperative microperforation occurred in seven out of 75 (9.3%) eyes with a temporally postoperative double anterior chamber in two eyes in the full-bed DALK group. Postoperative complications in the PK vs. the full-bed DALK groups respectively were: rejection (7.7% vs. 0%, P=0.015), high intraocular pressure (IOP) (46.2% vs. 1.3%, P<0.001), secondary glaucoma (9.6% vs. 0%, P=0.006), complicated cataract (19.2% vs. 0%, P<0.001), and wound dehiscence (9.6% vs. 0%, P=0.006). Conclusions: Both full-bed DALK and PK can offer long-term satisfactory visual outcomes for keratoconus. Graft rejection, secondary glaucoma, complicated cataracts, and constant endothelial cell loss were observed in eyes only after PK.

“…This has prompted the idea of using a longer-acting agent like C 3 F 8 gas to prolong the mechanical tamponading action in the anterior chamber. 6,7,16 Rajaraman et al 6 and Basu et al 7 both reported that single injection of intracameral C 3 F 8 gas was sufficient to treat the acute hydrops whereas Sharma et al 16 reported that five (35.7%) of their patients required repeated injections of intracameral C 3 F 8 gas.…”

“…7,8,16 Basu et al 7 reported that as high as 16% of the treatment cohort developed pupillary block postoperatively, necessitating an additional iridectomy to prevent or treat the complication. Taking into consideration the duration of action of the intracameral gas injection and the risk of complication, particularly secondary glaucoma, we advocated the use of C 2 F 6 gas, which is an intermediate-acting agent compared with SF 6 and C 3 F 8 gas.…”

“…L'hydrops cornéen ou kératocône aigu est une complication rare mais grave qui peut survenir au cours de l'évolution du kératocône [1,2]. Elle correspond à l'irruption massive d'humeur aqueuse dans le stroma cornéen suite à une rupture de l'endothélio-Descemet avec l'apparition brutale d'un oedème stromal et épithélial [3,4]. L'hydrops cornéen surviendrait chez 2,4 à 3 % des yeux avec un kératocône et bien que spontanément résolutif, il serait responsable d'une diminution de l'acuité visuelle liée à l'opacification cornéenne qui en résulte [3,4].…”

“…La tomographie en cohérence optique du segment anté-rieur (OCT-SA) est une technique d'imagerie non invasive de plus en plus utilisée pour l'analyse des pathologies cornéennes [4][5][6][7][8]. Grâce aux nouveaux OCT dit « spectral domain », il est aujourd'hui possible d'obtenir des images de haute résolution avec un temps d'acquisition très court et ainsi, de reconstruire des images parallèles à la surface de la cornée dites « en face ».…”
