“…The advantages of DALK are well documented in the literature [ 13 - 15 ]. A study by Hakeem in 30 eyes comparing manual versus big bubble DALK found better postoperative BCVA in the big bubble variety [ 16 ].…”

Purpose: This study aims to assess the postoperative results, variability, and complications of a hundred deep anterior lamellar keratoplasty cases. Study design and duration: This is an observational study. The study was conducted at Pak International Medical College (PIMC) for a duration of four years (January 2019-January 2023). Methodology: Our study collected information on a hundred cases of deep anterior lamellar keratoplasty (DALK) utilizing Anwar's big bubble technique, consisting of patients with keratoconus, superficial corneal scars, and macular dystrophy. Consenting patients had their pre and postoperative visual acuities and keratometry readings recorded. Overall success and complications were recorded and compared with the present literature. Results: Big bubble formation was achieved in 87% (n = 87) eyes and not achieved in 13% (n=13). There was a significant reduction in keratometry values after the procedures as well as improved vision in all patients, with 84% reporting significant improvement. Descemet membrane exposure was achieved in 91% (n=91). Complications included the failure of Anwar’s big bubble formation in 13% (n=13) patients and the failure to expose Descemet’s in nine patients (9%). Conclusion: DALK using the big bubble technique is a safe and effective procedure in patients with corneal diseases who have a healthy Descemet membrane and endothelium.
