Conductive keratoplasty for the treatment of presbyopia: comparative study between post- and non-LASIK eyes

Figures & data

Figure 1 Cylindrical change from preoperative for non- and post-LASIK groups. One week, 1 month, 3 months, 6 months, and 1 year postoperative absolute cylinder change from preoperative was calculated for the non- and post-LASIK groups.

Table 1 Nomogram for conductive keratoplasty

Intended correction	Number of spots	Optical zone
0.5–1.0 D	8	7 mm
1.0–1.5 D	16	7–8 mm
1.5–2.0 D	8	6 mm
2.5–3.0 D	16	6–8 mm
3.0–3.5 D	16	6–7 mm

Figure 2 The error from the intended correction for non- and post-LASIK groups. The predictability at 1 week, 1 month, 3 months, 6 months, and 1 year postoperative for the non- and post-LASIK groups was evaluated by calculating the distance of manifest refraction spherical equivalent value from the intended correction.

Figure 3 Comparison of corneal thickness, amount of correction made during LASIK, and residual corneal bed thickness after LASIK and the predictability at 3 months postoperative for both groups.
