“…An important advantage is that femtosecond laser pulses can be placed individually at different depths within the cornea, allowing accurate cuts and adjustment of individual cut patterns as well as more stable corneal and visual outcomes and higher surgical safety. [22][23][24][25][26] In our study, there was a statistically significant difference in UNVA 1 month postoperatively and at later examinations. No significant differences were detected between 3 months and 12 months after treatment.…”

“…The polygonal PK permits an accurate positioning of the flap and easier suturing of the flap to recipient bed, reducing rotational button slippage. The potential advantages of this new pattern compared to the round PK could include faster visual recovery and reduced induced astigmatism [21] .…”

“…Another reported option is to create angle-shaped trephination profiles with 'decagonal keratoplasty' [21] . The aim of these modifications is to improve the fitting of the donor button into the recipient cornea, thus increasing the rotational stability of the graft ( fig.…”

“…The decagonal keratoplasty profile was accomplished with a 40 kHz FSL ( fig. 4 ) using the same diameter of 8.0 mm on the donor and recipient with a cutting angle of 90° and using a mixed suture with 10 sutures on the corners of the decagon and a continuous 10 steps on the sides [21] . The polygonal PK permits an accurate positioning of the flap and easier suturing of the flap to recipient bed, reducing rotational button slippage.…”

The continuous evolution of corneal transplantation has recently demonstrated that the surgical approach based on selective lamellar keratoplasty represents the gold standard for the treatment of corneal disease. The replacement of the diseased corneal layers via anterior lamellar or endothelial keratoplasty clearly gives advantages to patients in terms of safety and outcomes. However, the classical method of penetrating keratoplasty has also recently undergone evolution and refinements. The introduction of femtosecond laser technology to clinical practice, after its wide use for refractive surgical corneal procedures, allowed for a significant refinement in terms of precision and customization of both penetrating and lamellar keratoplasty. The main advantages of using femtosecond lasers are represented by the possibility of performing complex-shaped trephination in both the donor and recipient tissues (for example, top-hat or zig-zag cut profiles) and the great precision of lamellar dissection. However, cut quality and interface smoothness still represent critical points to be improved.

“…It has been claimed that the decagonal shape decreases the torque effect associated with a circular graft during suture placement and allows a stable fitting of the graft into the recipient, because it provides the strength of a circular shape with the stability given by the angles of the polygonal design 14. The diameter of the posterior surface of the donor can be adjusted in F-PKP according to different purposes.…”
