ABSTRACT
Aims:
To determine the clinical efficacy of modified deep anterior lamellar keratoplasty (DALK) for the treatment of advanced‑stage keratoconus with steep curvature. Materials andMethods:
In this interventional, non‑comparative case series, 30 patients with advanced stages of keratoconus and curvature of more than 60 D underwent a modified DALK procedure. In this technique, after big‑bubble formation, posterior stromal lamella was cut and removed 5 mm centrally (baring Descemet’s membrane completely) with posterior stromal layer remaining peripherally.Results:
The study included 30 eyes (30 patients with a mean ± SD age of 25 ± 5.4 years). The follow‑up examination was performed for all participants up to 12 months after the surgery. The mean uncorrected visual acuity (UCVA) increased from 20/800 before the surgery to a subsequent 3/10 (P = 0.12). Likewise, best spectacle corrected visual acuity (BSCVA) improved, reaching 6/10 postoperatively (former quantity 20/200) (P = 0.18). In addition, mean keratometry and keratometric astigmatism managed to achieve considerable improvement, from 58.8 ± 5.4 D to 46.5 ± 2.1 D and 7.8 ± 2.1 to 4.54 ± 1.54 D, respectively (P = 0.52). Descemet’s membrane wrinkling was not seen in any patient postoperatively.Conclusions:
This technique is effective in restoring acceptable vision and corneal regularity in advanced cases of keratoconus with a curvature more than 60 D who are also at risk of Descemet’s membrane wrinkling after DALK. Therefore, this procedure could prevent from Descemet membrane wrinkling in such cases.
