“…However, astigmatism still appears as the most important problem that we are confronted with, affecting patient satisfaction and vision quality in the postoperative period pursuant to surgery of cataract, which is a particular old age disease [8,9]. In order to minimize this current problem, corneal relaxing incisions and toric intraocular lenses eliminating the astigmatism when placed on a specific axis are being utilized [10]. Nevertheless, despite these methods, success cannot always be granted and problems about postoperative vision quality may occur.…”

Objectives. To analyze the corneal astigmatism and axial length values in cataract surgery candidates. Methods. The files of patients who undergone cataract surgery between November 2012 and November 2013 were retrospectively selected and reviewed. The preoperative corneal keratometry measurements in the flat and steep axis and the axial lengths of the patients were recorded. Results. The study comprised of 449 eyes of 449 patients with a mean age of 68.6±9.8 (range; 40-90) years. The mean axial length value was 23.1±1.0 mm; mean corneal astigmatism was 1.00±0.70 D. The corneal astigmatism was 1.00 D or less in 315 eyes (70.1%); between 1.00 and 2.00 D in 99 eyes (22%); and 2.00 D or more in 35 eyes (8%). With-the-rule astigmatism was present in 51% of the patients, against-the-rule astigmatism was present in 32% of the patients, and oblique astigmatism was present in 17% of the patients. We observed an increase in against-the-rule astigmatism (p=0.032) and oblique astigmatism with age (p=0.040). Conclusions. The current study is the most populous study in this field of research ever carried out in our country. The mean axial length in our study in comparison to Chinese and German populations was found to be shorter.

“…4 Astigmatism can be corrected by implanting a toric IOL or by changing the corneal curvature by LASIK or similar procedures, or by placing relaxing incisions at the steepest meridian to flatten the corneal curvature. 5 Relaxing incisions may correct up to 3 D of astigmatism, whereas toric IOLs can correct up to 8 D of astigmatism. 6 There are benefits and harms associated with toric IOLs and relaxing incisions.…”

“…Namely, refractive errors such as hyperopia and myopia combined with presbyopia, and also plano-presbyopia, cannot be fully treated with refractive surgery on the cornea. Laser corneal ablation is highly effective in correction of refractive errors and may be the best option for younger population [21]. However, for patients aged 45 or more, only distance vision can be corrected by laser ablation, but the problem of presbyopia remains.…”

Introduction: The first generations of multifocal intraocular lenses (MFIOLs) were designed to provide patients good distance and near vision, but intermediate was not satisfactory. Trifocal, a bifocal of low-add and quadrifocal MFIOLs were invented, offering possibility to correct vision for distance, near, and intermediate tasks. The novel IOL, extended range of vision (EROV), is covering mostly intermediate and distance vision, with lower level of photic phenomena. Patients and methods: We have evaluated visual results in 4408 eyes implanted with different MFIOLs in 12 years period (2004-2016). Postoperative uncorrected visual acuity for far, intermediate, and near was evaluated. Postoperative satisfaction and complication rate and management of complications are presented. Results: In the first generation MFIOLs, almost 70% of eyes gained uncorrected distance visual acuity of 1.0. Uncorrected near visual acuity was J1-J2 in 95% of eyes with diffractive IOLs. Modern MFIOL designs enabled improvement of vision at intermediate distance, without compromising vision at far and near. Conclusion: With the first generations of MFIOLs, good distance and near uncorrected vision was achieved. With novel MFIOLs a very good uncorrected vision was achieved at far, intermediate and near, while with EROV lens, near vision was less satisfactory, but patients had less photic phenomena.

Update on astigmatism management

Abstract: Cataract surgery has evolved into a refractive procedure, in which not only the sphere but also cylinder errors can now be confidently corrected. Careful assessment and surgical planning of astigmatism should not be an option, but essential components of cataract surgery.
