Purpose:
|
To investigate recipient and operative factors that can influence the rate of a bare Descemet membrane (DM) achievement during deep anterior lamellar keratoplasty (DALK) in keratoconus.
|
|
Methods:
|
In this retrospective comparative study, a total of 290 (153 right) consecutive eyes from 257 (179 male) keratoconus patients that underwent DALK with the big-bubble technique were enrolled. factors including patient age and sex , history of contact lens wear, the presence of Vogt’s striae or superficial opacities, keratometric readings, central and peripheral corneal thickness, anterior chamber depth, vitreous length, and trephination size.
|
|
Results:
|
The surgery was completed as DALK in 289 of 290 eyes and a bare DM was successfully achieved in 229 (79.2%) eyes. The recipient sex and trephination size significantly influenced the success rate of big-bubble formation. The female sex decreased the odds of bare DM achievement by 0.44 times (P=0.02). For each 0.1-mm increase in the trephination size, the odds of the successful big-bubble formation increased by 1.36 times (P=0.03).
|
|
Conclusion:
|
Among different factors, recipient sex and trephination size significantly influenced this rate; female sex predicted a less likelihood of big bubble formation while large trephination size was associated with an increase in the chance of bare DM achievement
