Efficacy and Safety of Hole Implantable Collamer Lens in Comparison with Original Implantable Collamer Lens in Patients with Moderate to High Myopia.
Conclusion: The two groups had similar clinical effectiveness in terms of unaided visual acuity, best corrected visual acuity, intraocular pressure and spherical aberration induction. The new Hole-ICL group (Group B) needed no preoperative laser peripheral iridotomies or intraoperative iridectomy. PMID: 29927184 [PubMed - in process]
To compare the outcomes of topography-guided (TG) and wavefront-optimized (WFO) surgery in patients undergoing laser in situ keratomileusis (LASIK) for myopia.
To compare the outcomes of topography-guided and wavefront-optimized surgery in patients having laser in situ keratomileusis (LASIK) for myopia.
To assess the regional changes in corneal shape after femtosecond laser –assisted laser in situ keratomileusis (FS-LASIK) in patients with different myopia extents.
To study eyes with 20/10 uncorrected distance visual acuity (UDVA) 3 months and 12 months after topography-guided LASIK for myopia and myopic astigmatism, and to identify factors predictive of this excellent level of visual acuity.
To compare the effective optical zone (EOZ) after small-incision lenticule extraction (SMILE) and femtosecond laser –assisted laser in situ keratomileusis (FS-LASIK).
Operating on a fellow physician is always a particular challenge for any surgeon. In this case, the surgeon is faced with a situation that nowadays probably would not have been created in the first place: LASIK in an eye with high myopia of −9.00 D.
This patient was referred with decreased visual quality over the past year. He presented with cataract and previous small-zone decentered myopic ablation for high myopia with increased coma and spherical aberration. The corneal topography decentration is not as severe as it seemed considering the spectacle-corrected visual acuity achieved by the patient. Nowadays, LASIK would not be indicated for this amount of myopia.
This is an interesting case of an active surgeon, who had LASIK in both eyes for high myopia 17 years ago at the age of 45, and now has increased aberrations and has developed cataracts. His pupils are approximately 2.0 mm in both eyes, and although the scan lighting conditions are not mentioned, the relatively small pupils might have contributed to the patient being reasonably satisfied with his vision and having had an active lifestyle for many years. Therefore, I would not consider regularizing the cornea before cataract surgery.
This patient is a 62-year-old male physician who presents with moderate nuclear sclerotic cataracts and who is very motivated to achieve spectacle independence. Complicating the picture is his history of bilateral LASIK with small inferiorly decentered ablation zones for correction of high myopia. His corneas also show moderate levels of with-the-rule astigmatism and significant higher-order aberrations (HOAs) (vertical coma and spherical aberration) on wavefront analysis.
A 62-year-old physician presented with decreased visual quality over the past year. He had a history of laser in situ keratomileusis (LASIK) in both eyes for high myopia in 2001 for a refraction of −9.00 diopters (D) (patient information). No medical records for this previous procedure were presented (the surgery was performed in another city). The patient said that after the LASIK, his vision was good for distance in both eyes for a few years (reading spectacles were needed just after the p rocedure) and the visual quality was never sharp, although it was “acceptable.” There was no history of dry eyes an...
