Conclusions Both Epi-LASIK and LASIK show their own characteristics in increased higher-order aberration at smaller and larger pupil sizes, and may create different effects on optical quality for photopic (smaller pupil) and scotopic conditions (larger pupil). We speculate that the visual performance in the Epi-LASIK group may be better than in the LASIK group for the larger pupil size.

In this study, the authors initially described the corneal posterior shape by elevation and created a detailed evaluation reference database determining the shape of the corneal posterior surface in normal human eyes. Moreover, the authors retrospectively studied the data on corneal posterior elevation changes after LASIK and epi-LASIK for myopia and myopic astigmatism and evaluated the changes along four districts at center, paracenter, midperiphery, and periphery.

Conclusion: In spite of an excellent visual outcome, WFO Lasik induces significant higher order aberrations. Large ablation zones reduce the induction of spherical aberration.

A patient was treated bilaterally for myopia using laser in situ keratomileusis (LASIK). Preoperatively, there was no known risk factor for ectasia but a 20 μm between-eye difference in central mean corneal thickness was seen on the optical pachymetry map. Two years postoperatively, bilateral ectasia was diagnosed. This case suggests that abstention or surface ablation treatment may be a safer option than LASIK in patients showing central thickness asymmetry between eyes.Financial Disclosure: Neither aut

Conclusions: The 4-year results indicate that ICRS implantation is effective and safe in the correction of low myopia in patients for whom excimer laser surgery is contraindicated because of abnormal topography, including forme fruste keratoconus.

CONCLUSIONS: In post-LASIK myopic eyes, although a high correlation has been shown between Pentacam and UP measurements, Pentacam tends to overestimate CCT compared to UP. Pentacam probably cannot be used interchangeably with UP in post-LASIK eyes for myopia. PMID: 20815096 [PubMed - in process] (Source: European Journal of Ophthalmology)

CONCLUSION:Mean decentration was higher in hyperopia than in myopia. Most of the decentration may be attributed to inferior decentration. Pupillary offset values were the factor most significantly correlated to the amount of decentration in all cases.
