To assess the astigmatic changes between before and after complete suture removal (ROGS) in eyes with keratoconus undergoing keratoplasty.
Moorfields Eye Hospital Dubai
Consecutive case series involving 42 eyes undergoing either Penetrating (PK, N=32) or Big Bubble Deep Anterior Lamellar Keratoplasty (DALK, N=10). Comparison were also made between Manual and Femtosecond laser techniques (Manual PK [N=17], Femto PK [N=10], Manual DALK [N=4], Femto DALK [N=6]).
No statistically significant differences were detected in Mean Arithmetic Astigmatism Magnitude before ROGS between the groups: PK v DALK (5.29±2.49; 5.95±3.84 D; p: 0.64); Manual v Femto PK (4.65±2.17; 6.32±2.91 D; p: 0.15); Manual v Femto DALK (8.50±4.50; 4.25±1.97 D; p: 0.20); Manual PK v Manual DALK (4.65±2.17; 8.50±4.50 D; p: 0.23); Femto PK v Femto DALK (6.32±2.91; 4.25±1.97 D; p: 0.14). Likewise, no significant differences in astigmatism were detected following ROGS between the groups: PK v DALK (5.49±2.48; 6.65±3.48 D; p: 0.37); Manual v Femto PK (5.17±2.60; 5.57±2.18 D; p: 0.68); Manual v Femto DALK (6.62±3.45; 6.67±3.50 D; p: 0.99); Manual PK v Manual DALK (5.17±2.60; 6.62±3.45 D; p: 0.53); Femto PK v Femto DALK (5.57±2.18; 6.67±3.50 D; p: 0.54). The Vector computed ROGS-induced astigmatism was greatest in the Manual DALK group (5.49±1.82 D) and lowest in the Femto DALK group (3.18±1.87 D).
PK and DALK induced a similar magnitudes of postoperative and post-ROGS astigmatism and the use of the femtosecond laser did not cause a significant reduction in the astigmatism.
